| Abstract: | Based on the topographic and geologic conditions of the dam site zone of a certain hydropower station, a 3D finite element metgid regression model is made for the geo-stress field in dam zone,by using the observed data from 21 observation points.It revealled the basic feathers and distribution laws of initial geo-stress in this geologic area.The effect of geologic structure and two shores structure face on GEO-stress field is studied. |
