黄河李家峡典型岩坡变形破坏的水效应研究

STUDY ON THE EFFECT OF WATER ON DEFORMATION DAMAGE OF THE TYPICAL ROCK SLOPE OF LIJIAXIA GORGE ON THE YELLOW RIVER

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。

The deformation damage of high and steep rock slope at the upper reach of the Yellow River is affected by many factors, among which the effect of water is very obvious and consists of both static and dynamic effects of water. Using numerical simulation method, the effect degree and way were studied, respectively, from the softening of underground water, the water pressure of reservoir banks or the hydrostatic pressure and the pore water pressure, as well as the river erosion, the bank reform, the seepage force resulted from the precipitation and the reservoir sluicing.
