水压致裂法三维地应力测量及其修正和工程应用

3D geostress measurement by hydrofracturing technique and its engineering application

摘要: 叙述了水压致裂法三维地应力测量在水布垭枢纽中的具体应用,并对经典理论( 钻孔轴向就是地应力的一个主方向的假定) 整理的实测成果,进行了修正

Abstract: The method and modification of 3D geostress measurement by hydrofracturing technique is proposed in this paper . Unlike the conventional hydrofracturing method, it does not adopt the hypothesis that one of the principal stress direction is parallel to the borehole axis. This method has been applied in the Shuibuya Hydroelectric Project .
