| Abstract: | The preliminary position of bridge foundation of Yaojiawan bridge in Yichang-Wanzhou railway is determined by the method of empirical equation and stress analysis.According to the stability analysis of the fault at different bridge foundation positions,a rational bridge foundation position is selected.The bridge foundation position is verified by the strength analysis of the rock mass of slope,and the bridge foundation position is determined as 19m in horizontal distance. |

| Keywords: | bridge foundation rock slope stability stress rock mass strength |
