摘要
木文对小天都水电站气垫调压室 5个测点共 15个钻孔的水压致裂法应力测量结果进行了深入的分析 ,得到最大主应力约 2 0MPa左右。文中还结合工程地质 ,讨论了电站区的三维应力特点及其对工程设计的参考作用。
In this analyzed paper, the results of three-dimensional stress measurement by hydraulic fracturing are analyzed in 15 drillholes (5 measuring point) in the surge chamber of Xiaotiandu Hydro-power Station, the greatest principal stress value about 20MPa is obtained. Combined with the state of engineering geology, the regional three-dimensional stress feature is discussed, it's helpful for the engineering design.
