摘　　要：本文对优势结构面理论进行了简单的介绍，并应用该理论对古水水电站坝址岩体稳定性进行研究，借助赤平极射投影法对受优势面控制的岩体变形破坏工程地质模型进行分析，得出坝址区的优势结构面对大坝的稳定性是有利的。This paper briefly introduces the advantageous structural plane theory and applies this theory in the stability analysis of Gushui Hydropower Station Dam Site. It also conducts analysis on engineering geologic model of rock mass damaged by deformation, which is controlled by the advantageous plane, by utilizing the stereographic projection method, and draws the conclusion that the advantageous structural plane at dam site is favorable to the dam Stability.
