This book was released on 2006 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Virginia Department of Transportation (VDOT) is currently developing an asset management system, identifying various transportation assets for inclusion in the system. Rock slopes along Virginia's highways can be viewed as assets that need to be managed proactively in order to maintain a safe and effective transportation network. The benefits of rock slope management are expected to be similar to those derived from bridge and pavement management systems, including inventory, condition, and estimate of maintenance needs. An established rock slope management tool designed to facilitate proactive management of rock slopes is available by way of the Rockfall Hazard Rating System (RHRS), initially developed for the Federal Highway Administration by the Oregon Department of Transportation. The purpose of the RHRS is to allow agencies to prioritize rock slopes for remediation based on a risk assessment and to facilitate the allocation of funds for needed remediation. VDOT adopted a modified version of the RHRS, which could serve an important role in a comprehensive rockfall management program. Core elements of such a program, including technical training and setup of a GIS database, were implemented in this study to assist VDOT in identifying potentially hazardous rock slopes and establishing funding priorities for mitigation projects.

This book was released on 2017 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Most routes in mountainous areas suffer from rock falling, rolling and bouncing risk. There are many computer programs concerned with simulating the rockfall problem, and whereas they have the same purpose, they however differ in the input data that's needed to simulate the problem, and they also differ in the way of processing and kind of output. This study used Rocfall® and the Colorado Rockfall Simulation Program (CRSP®) to simulate sixty-three models of varying slope geometry, where only the slope geometry is changed with the same material properties for both the slope and the rocks. Both programs were fast and easy in the data input stage, whereas the 'Barrier' feature of Rocfall added an advantage over the CRSP program in enhancing the solving of the rockfall problem. Also, 'Data Collectors', 'Results Animation' and 'Graph Distribution' on the slope profile help display the analysis results in Rocfall. Generally, the Rocfall and CRSP program results are not similar. The rock falls at a different angle in each program; CRSP is closest to the Physics theory, so that affects the results. Also, the rocks can be located just at (X=0) in CRSP that affects the allowed number of rocks falling along slope profile. Despite of the differences between the Rocfall and CRSP programs, their results indicated the slopes with 900 slope angle is the ideal slope geometry for rockfall problem. For vertical slopes, no rocks passed the shoulder edge onto highway in both programs. CRSP results indicated that the percentage of rocks that reach the highway are increasing when the slope height increases"--Abstract, page iii.

Available in PDF, EPUB and Kindle. Book excerpt: The stability of rock slopes is an important issue in both civil and mining engineering. On civil projects, rock cuts must be safe from rock falls and large-scale slope instability during both construction and operation. In open pit mining, where slope heights can be many hundreds of meters, the economics of the operation are closely related to the steepest stable slope angle that can be mined. This extensively updated version of the classic text, Rock Slope Engineering by Hoek and Bray, deals comprehensively with the investigation, design and operation of rock slopes. Investigation methods include the collection and interpretation of geological and groundwater data, and determination of rock strength properties, including the Hoek Brown rock mass strength criterion. Slope design methods include the theoretical basis for the design of plane, wedge, circular and toppling failures, and design charts are provided to enable rapid checks of stability to be carried out. New material contained in this book includes the latest developments in earthquake engineering related to slope stability, probabilistic analysis, numerical analysis, blasting, slope movement monitoring and stabilization methods. The types of stabilization include rock anchors, shotcrete, drainage and scaling, as well as rock fall protecting methods involving barriers, ditches, nets and sheds. Rock Slopes: Civil and Mining Engineering contains both worked examples illustrating data interpretation and design methods, and chapters on civil and mining case studies. The case studies demonstrate the application of design methods to the construction of stable slopes in a wide variety of geological conditions. The book provides over 300 carefully selected references for those who wish to study the subject in greater detail. It also includes an introduction by Dr. Evert Hoek.
