Available in PDF, EPUB and Kindle. Book excerpt: An essential guide to improving preliminary geotechnical analysis and design from limited data Soil Properties and their Correlations, Second Edition provides a summary of commonly-used soil engineering properties and gives a wide range of correlations between the various properties, presented in the context of how they will be used in geotechnical design. The book is divided into 11 chapters: Commonly-measured properties; Grading and plasticity; Density; Permeability, Consolidation and settlement; Shear strength; California bearing ratio; Shrinkage and swelling characteristics; Frost susceptibility; Susceptibility to combustion; and Soil-structure interfaces. In addition, there are two appendices: Soil classification systems; and Sampling methods. This new, more comprehensive, edition provides material that would be of practical assistance to those faced with the problem of having to estimate soil behaviour from little or no laboratory test data. Key features: Soil properties explained in practical terms. A large number of correlations between different soil properties. A valuable aid for assessing design values of properties. Clear statements on practical limitations and accuracy. An invaluable source of reference for experienced professionals working on geotechnical design, it will also give students and early-career engineers an in-depth appreciation of the appropriate use of each property and the pitfalls to avoid.

Download or read book Frost Susceptibility of Soil written by Edwin J. Chamberlain and published by . This book was released on 1981 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods of determining the frost susceptibility of soils are identified and presented in this report. More than one hundred criteria were found, the most common based on particle size caharacteristics. These particle size criteria are frequently augmented by information such as grain size distribution, uniformity coefficients and Atterberg limits. Information on permeability, mineralogy and soil classification has also been used. More complex methods requiring pore size distribution, moisture-tension, hydraulic-conductivity, heave-stress, and frost-heave tests have also been proposed. However, none has proven to be the universal test for determining the frost susceptibility of soils. Based on this survey, four methods are proposed for further study. They are the U.S. Army Corps of Engineers Frost Susceptibility Classification System, the moisture-tension hydraulic-conductivity test, a new frost-heave test, and the CBR-after-thaw test. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The magnitude and variation of forces and shear stresses, caused by frost heaving in Fairbanks silt and the adfreeze effects of a surface ice layer and a gravel layer, were determined as a function of depth by using electric strain gauges along the upper 2.75 m of a pop pile, 30.5-cm I.D. x 0.95-cm wall, and an H-pile, 25.4-cm web x 85 kg/lineal m. The peak frost heaving forces on the H-pile for three consecutive winter seasons (1982-1985) were 752,790 and 802 kN, respectively. Peak frost heaving forces on the pipe pile of 1118 and 1115 kN were determined only for the second and third winter seasons. Maximum average shear stresses acting on the H-pile were 256,348 and 308 kPa during the three winter seasons. Maximum average shear stresses acting on the pipe pile were 627 and 972 kPa for the second and third winter seasons. Ice collars were placed around the tops of both piles during the first and third winter seasons to measure the adfreeze effects of a surface ice layer. The ice layer may have contributed 15 to 20% of the peak forces measured on the piles. A 0.6-m-thick gravel layer replaced the soil around the tops of both piles for the second and third winter seasons to measure the adfreeze effects of a gravel backfill. The gravel layer on the H-pile may have contributed about 35% of the peak forces measured. Maximum heaving forces and shear stresses occurred during periods of maximum cold and soil surface heave magnitude. These were not related to the depth of frost penetration for most of the winter since forst was present at all depths extending to the permafrost table. (mjm).

Available in PDF, EPUB and Kindle. Book excerpt: The report presents a description of the equipment and procedures used in the laboratory test of the relative frost susceptibility of different soils on Corps of Engineers construction projects and includes typical results of freezing tests of natural soils. The test uses a slow unidirectional freezing of a 6-in. high, remolded or undisturbed soil specimen with water available at the base (open system). The heaving rate measured during the test is used as the basis for classification of the frost susceptibility potential of the soil. This type of test, which measures heaving rate, is considered most versatile and adaptable for evaluating the effects of numerous soil parameters on frost heave. (Author).

Download or read book Experiments to Simplify Frost Susceptibility Testing of Soils written by C. W. Kaplar and published by . This book was released on 1971 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments conducted at USA CRREL in recent years indicate that the two weeks or so required for the frost susceptibility testing of soils with previous procedures can be shortened considerably. Results of these experiments show that useful frost heaving data can be obtained in a matter of 2 or 3 days by a more rapid freezing technique. Results of experiments in which soil specimens were exposed to a constantly maintained temperature are presented. Data show that heave rate in laboratory experiments is a variable, not a constant, of a soil and is strongly dependent upon the heat extraction rate. The important role of frost susceptibility testing and soil evaluation for highway design is discussed. The suitability of equipment for use in conducting frost-heaving tests is also discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to classical soil mechanics and foundation engineering, and applies these principles to agricultural engineering situations. Theoretical design formulae are given, plus tables and graphs dealing with bearing capacity factors, wall pressure factors, soil cutting numbers and soil mechanical properties. Many example problems of design and analysis are solved in the text, and there are unsolved problems given for each chapter.The text begins with descriptions of soil origins and classification systems, including agricultural classification schemes, and then introduces classical concepts of soil strength and strength measurement techniques in the laboratory and in the field. Soil mechanics is applied to the design of shallow foundations, and the design formulae as well as tables of bearing capacity factors for design use are provided. New research and design findings in the specialized area of tall and heavy farm silos are also given, in addition to deep pile foundation design for heavy structures on very soft soils. Water flow in soils is treated, together with stability of ditch bank slopes and small earth dams, design of retaining walls and pressure pressures in bins and silos, soil erosion and protection methods, soil cutting and tillage design methods, soil compaction analysis, the use of geotextiles and problems of soil freezing.The book is directed primarily at professional university students in Agricultural Engineering, but will also be of interest to scientists working in other engineering branches, landscape architecture, soil physics and the like.

Download or read book Applications of Soil Physics written by Daniel Hillel and published by Elsevier. This book was released on 2012-12-02 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of Soil Physics deals with the applications of soil physics and covers topics ranging from infiltration and surface runoff to groundwater drainage, evaporation from bare-surface soils, and uptake of soil moisture by plants. Water balance and energy balance in the field are also discussed, along with tillage and soil structure management. The development and extension of Penman's evaporation formula is also described. This book is comprised of 14 chapters and begins with a systematic description of the field-water cycle and its management, with emphasis on infiltration and runoff; redistribution and drainage; evaporation and transpiration; and irrigation and tillage. Subsequent chapters focus on transpiration from plant canopies; freezing phenomena in soils; scaling and similitude of soil-water phenomena; spatial variability of soil physical properties; and movement of solutes during infiltration into homogeneous soil. Concepts of soil-water availability to plants are considered, together with principles of irrigation management and the advantages and limitations of drip irrigation. This monograph is intended for upper-level undergraduate and graduate students of the environmental, engineering, and agronomic sciences.

Division of Building Research and published by Division of Building Research, National Research Council. This book was released on 1968 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ice lenses in natural soil are normally formed in a thermal gradient regime, and this permits the development of an undulating frost line if a range of pore sizes exists. Evidence is presented that suggests that the undulating nature of the ice-water interface permits the ice lens to form over the smaller pores of the system. Although fractions with only a limited particle size range have been studied, the results support the use of particle size as a valid basis for assessing frost susceptibility. (Author).
