| Abstract: | 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. |
