Download or read book Evaluation of Bridge-scour Data at Selected Sites in Ohio written by K. S. Jackson and published by . This book was released on 1996 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scour data collected during 1989-1994 were evaluated to determine whether pier scour and contraction scour occurred at 22 bridge sites in Ohio. Pier-scour depths computed from selected pier-scour prediction equations were compared with measured pier-scour depths, and the accuracy of the prediction equations were evaluated. Observed pier-scour relations were compared to similar relations developed through laboratory research. Mean streambed elevations were evaluated to determine the depth of contraction scour. Channel stability was assessed by use of mean streambed elevations at the approach section. Ground-penetrating radar was used at all sites to investigate the presence of historical scour.

Available in PDF, EPUB and Kindle. Book excerpt: A need existed to efficiently predict the potential scour that could be expected at nearly 20,000 existing off-system bridges in the State of Kansas to assign a National Bridge Inspection Standards (NBIS) Item 113 coding. A customized methodology for scour evaluation was developed through the guidance of TranSystems Corporation, The Kansas Department of Transportation, and the Federal Highway Administration. This thesis presents a procedure to rapidly assess the scour potential at existing bridges. This procedure consists of a prioritization method and routines to rapidly estimate scour components outlined in FHWA guidelines. Key to the successful implementation of this procedure is all information including bridge plans, historic inspection records, historic photographs, and current photographs were digitized, geo-referenced, and incorporated into GIS software. This procedure was validated on approximately 300 bridges and, at the time this report was written, has been applied to over 8,000 existing off-system bridges in the State of Kansas. The procedure was beneficial because it is repeatable, the information is easily obtained at a relatively low cost, it requires multiple sets of eyes on every bridge, it is efficient, it accounts for the main scour components outlined within HEC-18, and the results show good correlation with HEC-18 results. Although this procedure was developed for use in the state of Kansas, it may be applicable for use in other states. However, before doing so an evaluation of the site specific information should be performed and if necessary modifications should be made to the procedure to account for regional issues. The rapid assessment should only be administered by an Interdisciplinary Scour Team having expert knowledge with regards to structural, hydraulic, and geotechnical engineering.

This book was released on 2009 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridge scour is the term which describes the erosion of soil surrounding a bridge foundation due to water. Bridge scour can cause the reduction of the load carrying capacity of bridge foundations, excessive foundation settlements, and damage to bridge abutments. Bridges with foundations that are unstable for calculated and/or observed scour conditions are termed scour critical bridges. Approximately 25,000 bridges in the United States are classified as scour critical and about 600 of them are in Texas. This designation comes in part from the use of over-conservative methods that predict excessive scour depths in erosion resistant materials. Other methods have been developed to eliminate this over-conservatism but are uneconomical because they require site-specific erosion testing. The major contribution of this dissertation is a new method to assess a bridge for scour and erosion classification charts which categorizes the erodibility of geomaterials according to conventional engineering properties. The new method is a three level Bridge Scour Assessment (BSA) procedure which is relatively simple and economical. It does not require site-specific erosion testing and eliminates the over-conservatism in current methods. The first level, BSA 1, uses charts that extrapolate the maximum scour depth recorded during the life of the bridge to obtain the scour depth corresponding to a specified future flood event. The second level, BSA 2, determines the maximum scour depth and is carried out if BSA 1 does not conclude with a specific plan of action for the bridge. The third level, BSA 3, determines the time dependent scour depth and is carried out if BSA 2 does not conclude with a specific plan of action. The scour vulnerability depends on the comparison between the predicted and allowable scour depths. The 11 case histories used to validate the new method showed good agreement between predicted values and field measurements. BSA 1 was then applied to 16 bridges. In this process, 6 out of 10 bridges classified as scour critical by current methods were found to be stable. These results show that the new method allows for more realistic evaluation of bridges for scour while not requiring site-specific erosion testing.
Book Synopsis Bridge Scour Monitoring Methods at Three Sites in Wisconsin by : J. F. Walker
Download or read book Bridge Scour Monitoring Methods at Three Sites in Wisconsin written by J. F. Walker and published by . This book was released on 2005 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the nearly 11,500 bridges in Wisconsin, 89 have been assessed with critical scour conditions. The U.S. Geological Survey, in cooperation with the Wisconsin Department of Transportation, the Marathon County Highway Department, and the Jefferson County Highway Department, performed routine monitoring of streambed elevations for three bridges. Two monitoring approaches were employed: (1) manual monitoring using moderately simple equipment, and (2) automated monitoring, using moderately sophisticated electronic equipment. The results from all three sites demonstrate that both techniques can produce reasonable measurements of streambed elevation. The manual technique has a lower annual operating cost, and is useful for cases where documentation of long-term trends is desired. The automated technique has a higher annual operating cost and is useful for real-time monitoring of episodic events with short time durations.
