摘要

清江水布垭水利枢纽工程地下厂房区水压致裂法地应力测试成果表明：地下厂房区是以自重为主导的应力场，为中等地应力水平地区；地应力场的构成符合该地区地质力学机制。

Abstract

his paper presents the principle and methods of hydro-fracturing goestress measurement in underground plant area of Shuibuya Project on Qingjiang River. The test result shows that the constitute of geo-stress field accords with the geo-mechanics mechanism of this area, he gravitational stress is predominant in the geo-stress field ,which belongs to medium geo-stress level.
