摘　　要：万家寨水利枢纽工程进行了３个钻孔的水压致裂地应力测量。取得了该区最大水平主应力、最小水平主应力量值及最大水平主应力方向。根据测试结果对本区应力状态进行了分析，并对大坝及地下泵站的稳定性进行了讨论。Hydrofracturing insitu stress mesasurements of three boreholes in Wanjiazhai key water control project have been carried out. The Maximum and the minimum horizontal stresses and the direction of the maximum horizontal stress are obtained. According to the test results, the stress state of this area is analyzed. The stability of the dam and the undergroundl pump station are discussed also.
