国外水电工程地震风险性评估方法与国内有很大不同，一般采用确定性方法和概率性方法，本文对这两种方法进行了探讨。确定性方法比较简单，对资料的要求相对较低一些，而概率性方法比较繁琐，对资料的要求也较高，需要专门的计算软件。同时，确定性方法只能提供MCE、 MDE和OBE值，而概率性方法不仅能提供MCE、 MDE和OBE值，还能提供不同超越概率水平的地震动峰值加速度及其反应谱。

Foreign Hydropower Engineering seismic risk assessment methods are very different with the domes-tic,generally it uses general deterministic methods and probabilistic methods,the paper discusses two methods. Deterministic method is relatively simple ,relatively low number of requests for information ,and the probabilis-tic method is relatively cumbersome ,the data requirements are high ,the need for specialized computing soft-ware.Meanwhile,the deterministic approach can only provide MCE,MDE and OBE value and the probabilistic method can not only provide MCE,MDE and OBE value,but also provide different levels of probability of ex-ceedance of peak ground acceleration and response spectrum.
