水库滑坡位移与水动力耦合预测参数及其评价方法研究
Research on the prediction parameter and evaluation method of displacement coupled with water dynamics of the reservoir landslides
摘要
Abstract
On the basis of systematic analysis of the change rule of displacement and reservoir water level and the relation of their interaction,this paper proposes to take the reservoir water level variation as the loading dynamic parameter of landslides and to take its displacement as the response parameter,so as to determine the displacement response ratio parameter of dynamics increment and establish its prediction model by means of elastic-plastic theory and damage mechanics.Finally,taking the typical reservoir landslide of the Three Gorges Reservoir region-Huangtupo landslide as the example,this paper completes the calculation of displacement response ratio of dynamics increment of G02 and G07 monitoring points of Huangtupo landslide by using the displacement response ratio of dynamics increment prediction model.Meanwhile,the stability of the landslide is simulated and analyzed by using the Geostudio software.The characteristics of the displacement response and the evolution law of the slope stability show that the curves of displacement response ratio of dynamics increment of monitoring points basically agree with the dynamic evolution law of the slope stability.The research results above indicate that the displacement response ratio of dynamics increment is an effective dynamics displacement appraisal parameter of reservoir landslides,so it can be effectively used in the prediction of the reservoir landslides.关键词
