Study on Failure Mechanism and Prevention Measures of Typical Rock Slope in Tibetan Plateau
Abstract:
The special geographical, climatic conditions and geological structure in Tibetan Plateau making high steep rock slopes along the valleys wide-spread in this area, and they are especially common in the construction of highways. In this study, geological genesis and potential sliding mode are discussed firstly, then numerical model results as well as actual data are used to analyze the cause and influence depth of unloading fissures. Finally, common problems exist in rock slope are summed up. Based on these, natural state, disturbed state and steady state after reinforcement are analyzed respectively. It is believed that rock slopes in this area should be considered to minimize unloading, changing their shapes, and should try to reinforce actively or take positive reinforcement measures, so that the disturbance caused by rock soil environment will be effectively controlled, and the ecological restoration work will be done.
