Abstract null null Heavy rainfall has long been recognized as a key factor in the triggering of landslides, as large amounts of precipitation generally have strong weakening effects on anti-sliding forces along slip surfaces. However, it remains to be understood why the catastrophic Xintan landslide in China was triggered by only moderate rainfall rather than the area's heaviest historical downpour. In this study, we demonstrate that a locked segment (a natural sustaining arch) at Jiangjiapo on ...

AbstractFailure of jointed rocks is highly dependent on the presence of rock bridges that exist across joint surfaces. It has long been assumed that such bridges are homogeneous orders, but continued investigation has found that, more often than not, they are a heterogeneous order. In this paper, the failure processes of generalised rock bridges (including two barriers and one which contains an inclusion) under compression with confinement are investigated experimentally and numerically. The imp...

Abstract Better understanding the evolutionary mechanism of landslides is very important to predict their occurrence based on firm scientific grounds. The stability of a rock slope is often dominated by one or more locked segments along a potential slip surface with a large bearing capacity to resist instability. We propose three preliminary categories for locked segments and develop a physical model for predicting the instability of rock slopes with locked segments, by coupling a one-dimensiona...

The focus of the present study is to explain the stair-step brittle deformation evolutionary pattern of the landslide and reveal the corresponding internal physical mechanism. Based on the ...
