Rock Slope Engineering Reference Manual. Part A: Engineering Geology Considerations and Basic Approach to Rock Slope Stability Analysis for Highways

摘要

The report deals with the basic considerations and factors that are necessary for the rational assessment of the stability and design of rock slopes. Such an assessment necessitates an estimate of the long-term performance as well as the immediate behavior of the slope. Factors such as discontinuities, groundwater, lithology and weathering, time factor, dynamic forces, etc. are discussed with this fundamental consideration in mind. Long-term stability assessment requires a quantitative assessment of the physical and mechanical properties of the rock mass which govern its strength, permeability and deformation characteristics. It is only with these considerations in mind, and with a basic understanding of the engineering geology, that the slope condition in terms of stability, remedial measures, etc. can be critically assessed.
