摘要: 水布垭水电枢纽拟建于清江干流深切峡谷地段,重力是决定坝址区岩体稳定与否的关键因素。该文采用三维有限元数值模拟的方法,对坝区岩体在重力作用下的应力场和位移场进行研究,为工程建设和坝区岩质边坡稳定性评价提供了重要依据。

Abstract: The Shuibuya hydroelectric project will be built in gorge morphology on Qingjang River, the gravitation is key factor which decides whether the rock in dam site is stable or not.In this paper, we study stress and strain field of rock body in dame site under the gravitative using 3-D finite-element simulation method, the result provides an important evidence for project construction and assessing the stability of rock slope.
