Study of Different Investigation Scales for Rock Slope Failure Susceptibility Evaluation, Analysis and Its Monitoring - Failure and Accumulation Characteristics for Rock Slopes Considering the Scale Effect Using Physical and Numerical Models

Due to the frequent extreme weather conditions in recent years, when the rock slopes are subject to naturaltriggering factors such as heavy rainfalls or earthquakes or artificial triggering factors, slope failure mayoccur and cause damages to the surrounding areas. To prevent or reduce the damages during and after rockslope failure, one has to capture the failure mechanisms, accumulation characteristics and the deformationfeatures of rock slope failure. From earlier researches about rock slope stability, it is well know that the rockslope failure is related to the rock slope types, and the geology conditions. However, to better plan for theevacuation routes or early warning system, it is also necessary to understand the deformation features andaccumulation characteristics under different conditions. Hence, it is the purpose of this main project tointegrate the information from different investigation scales, in order to facilitate the field investigationduring and after the rock slope sliding disaster. Further, in addition to the fact that the rock slope failure isrelated to the rock slope types and the geology condition, it is also crucial to explore the effect from differenttriggering factors, such as heavy rainfall, earthquakes or the size of the slopes. With the deformation andaccumulation features under different triggering factors, the rock slope failure mechanisms can be bettercharacterized. It is therefore expected that proper site investigation method may be proposed to better andmore efficiently understand the rock slope sliding condition, and innovative methods to analyze certain rockslope conditions are also suggested, in order to better predict the deformation and accumulation features ofcertain rock slopes with high failure susceptibility under given scenarios.
