| 摘 要： | 运用深钻孔套芯解除法对阳江抽水蓄能电站进行了三维地应力测量,并将测试结果与水压致裂法进行了比较.结果表明:工程区域应力属于中等水平,最大水平主应力方向由浅至深逐渐向NWW方向偏转,2种方法的测试结果基本相同.

| Abstract: | The overcoring method in deep borehole is one of the robust 3D geo-stress measuring methods at home and abroad. 3D geostress is measured by this method in Yangjiang pumped storage plant, and the measured results are compared with those of hydro-fracturing method measured results. The measured results indicate that the stress value of the project site is at the medium level, and the direction of the maximum horizontal turns to NWW along depth. The stress directions show a good accordance with the hydrofracturing results. |
