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。
The Wanjiazhai Water Control Project carried out the hydraulic fracturing stress measurement of three boreholes. The maximum horizontal principal stress, the minimum horizontal principal stress and the maximum horizontal principal stress are obtained. Based on the test results, the stress state in this area is analyzed and the stability of the dam and underground pumping station is discussed.
