摘要：

For risk analysis of slope, present study field is focused on the case of parameters of rock and soil material itself being random variables. The influence of natural multi-random factors is considered little. Only a few of scholars have done preliminary research on the risk of slope under random water level and horizontal earthquake force. But in hydrological risk analysis, just the failure risk caused by hydrostatic pressure was considered. The risk caused by seepage was ignored. In view of this shortage and on the basis of previous study, seepage factor is introduced and the risk of dam slope is evaluated under external random multi-loadings. As a typical example, the means is applied to downstream slope of Gouhou dam. In this project, the influence of permeated deformation and earthquake force are coupled and slope risk is evaluated under natural multi-random factors.
