Rock Slope Stability and Highway Rock Slope Design

摘要

The aim of the project is to develop a method for the engineering design of highway rock slopes based on a knowledge of the geological factors involved and the mechanics of rock slope failure. Progress during the first year is reported. This includes measurement schemes for both geologic factors, such as rock type, foliation, rock fracture, joint patterns and groundwater, and non-geologic factors such as altitude, aspect of the slope and height and length of slope. Multiple regression analyses will be used to reduce the number of interrelated factors and to point out the main factors that should be measured for a reasonable analysis. Progress has also been made on the model study of jointed rock slopes. Piles of aluminum, plastic, or wooden bars will be used to represent rock slopes in the study of failure mechanisms. An extensive bibliography on rock slope stability and related subjects is included.
