黄河上游李家峡段高陡岩坡变形破坏受多种因素控制，其中水的影响十分明显，主要包括水的静态效应和动态效应两方面。本文从地下水的软化作用、库岸水压力或静水压力、孔隙水压力，以及河流冲蚀、边岸再造、降雨引起的动水压力作用和水库泄水引起的动水压力作用等方面，结合数值模拟手段分别研究了它们对岩坡变形破坏的影响程度和方式
The deformation and failure of the high steep slope in the Lijiaxia section of the upper reaches of the Yellow River are controlled by many factors. Among them, the influence of water is obvious, including the static effect and dynamic effect of water. In this paper, from the aspects of softening effect of groundwater, water pressure or hydrostatic pressure of reservoir bank, pore water pressure, hydrodynamic pressure effect caused by river erosion, reengineering of bank, rainfall and hydrodynamic pressure caused by reservoir discharge, Simulation methods were studied on their impact on the rock slope deformation and damage degree and way
