Book Synopsis TBM Tunnelling in Jointed and Faulted Rock by : Nick R. Barton
Download or read book TBM Tunnelling in Jointed and Faulted Rock written by Nick R. Barton and published by CRC Press. This book was released on 2000-01-01 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical guide describes the stage-by-stage development of a method for predicting the penetration rate (PR) and the advance rate (AR) for tunnel boring machines based on an expanded version of the Q-value, QTBM. The author analyzes 145 TBM tunnels that total 1,000km in length. He then develops simple formulae to estimate PR and AR from the QTBM value and to back-calculate QTBM from performance data. The book quantitatively explains actual advance rates as high as five m/hr for one day or as low as 0.005 m/hr for several months. It also covers logging methods, empirical TBM tunnel support design, and numerical verification of support.
Book Synopsis Tunnel Boring Machines: Trends in Design and Construction of Mechanical Tunnelling by : A. Schulter
Download or read book Tunnel Boring Machines: Trends in Design and Construction of Mechanical Tunnelling written by A. Schulter and published by CRC Press. This book was released on 2020-08-26 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past ten years there was a worldwide trend towards increased use of Tunnel Boring Machines (TBM's). This trend covers a broad variety of applications ranging both from small diameters for sewers and other utilities to large diameters for double track railway and even three-lane highway tunnels. The response to this has been the development of both hard rock machines in the direction for application in soft ground, and soft ground TBM's to be used in soft rock. Parallel to the technical development of TBM's towards applications for longer tunnels, running through changing geological conditions, there are needs for the development of lining methods. 'TBM Tunnel Trends' an international lecture serie collection, aims to present the latest scientific and practical state of the art of TBM tunnelling, taking into consideration interactions between machinery and lining. 26 international highly recognized papers.
Book Synopsis TBM Excavation in Difficult Ground Conditions by : Nuh Bilgin
Download or read book TBM Excavation in Difficult Ground Conditions written by Nuh Bilgin and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The book relates experience of TBM drives in difficult geology, making use of case studies from Turkey to demonstrate the influence of the local geotechnical conditions on the selection of a tunnel boring machine and the selection of tools. There is an extensive description how various geological phenomena, such as for example transition zones, dikes, rock discontinuities, blocky ground, squeezing ground, swelling clays and high strength and abrasive rocks, can reduce the advance rate and what countermeasures can be introduced. There is also a discussion of necessary advance probing and safety measures. Since the presented practical experience from Turkey can also be applicable for other tunnel projects in difficult geology, the book represents a valuable source of knowledge for every tunneler.
Book Synopsis Mechanized Tunnelling in Urban Areas by : Vittorio Guglielmetti
Download or read book Mechanized Tunnelling in Urban Areas written by Vittorio Guglielmetti and published by CRC Press. This book was released on 2008-01-07 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internationally, the mechanized excavation of tunnels has intensified in the last two decades, as the number of tunnels being constructed for subways and railway underpasses increases. The subject of mechanized tunnelling in urban areas has not previously received the attention that it deserves, despite there being specific hazards associated with the construction of tunnels in metropolitan areas, including poor ground conditions, water tables higher than the level of tunnels, and subsidence leading to damage to the existing structures on the surface. The application of technologies for achieving the stability of the tunnel and for minimizing surface settlement is described in this book. Accurate characterization of the ground; rigorous assessment and management of risk from design to maintenance; the correct choice of a tunnel boring machine and a plan for the advancement of the tunnel; specific excavation procedures and real-time monitoring of excavation parameters are all discussed in this thorough work.
Book Synopsis On the Feasibility of TBM Drives in Squeezing Ground and the Risk of Shield Jamming by : Marco Ramoni
Download or read book On the Feasibility of TBM Drives in Squeezing Ground and the Risk of Shield Jamming written by Marco Ramoni and published by vdf Hochschulverlag AG. This book was released on 2010 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Squeezing ground represents a challenging operating environment as it may slow down or obstruct TBM operation. Due to the geometrical constraints of the equipment, relatively small convergences of 10-20 cm may lead to considerable difficulties in the machine area (sticking of the cutter head, jamming of the shield) or in the back-up area (e.g., jamming of the back-up equipment, inadmissible convergences of the bored profile, damage to the tunnel support). Depending on the number and the length of the critical stretches, squeezing conditions may even call into question the feasibility of a TBM drive. On account of this, and bearing in mind the steady increase in the number of tunnels excavated with TBMs through so-called "difficult ground conditions", the topic investigated in this PhD thesis is of great practical relevance.Based upon case histories reported in the literature, Part I sets out firstly to give an overview of the specific problems of TBM tunnelling under squeezing conditions. Part II presents a computational model which simulates accurately and efficiently the advancing TBM and the installed tunnel support in one single computational step applying the so-called "steady state method". Part III advances a number of theory-based decision aids, which will support rapid, initial assessments to be made of thrust force requirements. Part IV investigates the complex problem of the interaction between the advancing TBM, the consolidating ground and the lining. Emphasis is thereby placed on the effect of the gross advance rate and the effect of ground permeability on shield loading during regular TBM operation (the boring process including short standstills) and during a long standstill.

Book Synopsis Practical Guide to Rock Tunneling by : Dean Brox
Download or read book Practical Guide to Rock Tunneling written by Dean Brox and published by CRC Press. This book was released on 2017-04-11 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Practical Guide to Rock Tunneling fills an important void in the literature for a practical guide to the design and construction of tunnels in rock. Practical Guide to Rock Tunneling takes the reader through all the critical steps of the design and construction for rock tunnels starting from geotechnical site investigations through to construction supervision. The guide provides suggestions and recommendations for practitioners on special topics of laboratory testing, durability of rock and acceptance for unlined water conveyance tunnels, overstressing or deep and long tunnels, risk-based evaluation of excavation methods, contract strategies, and post-construction inspections. Key considerations and lessons learned from selected case projects are presented based on the author’s extensive international experience of over 30 years and 1000 km of tunneling for civil, hydropower, and mining infrastructure, including some of the most recognized projects in the world to date. Instead of revisiting all theory and concepts that can be found in other sources, this book contains the hard learned lessons from the author’s experience in the field of Rock Tunneling, gathered over 30 years of service.
