| Abstract: | Based on the analyses results of simple inference method and seismic focal mechanism and on the statistic results of measured geostress data, the direction of principal stress was derived and based on the analyses results of macro geological estimate and on the statistic results of measured geostress data the magnitude of principal stress was derived too. Then the evolution of geostress field accompanying with the down cutting of Yellow River and was simulated with FEM and the spatial distribution features of geostress were discussed. |
| Keywords: | hydropower station geostress field numerical simulation comprehensive assessment |
