摘要
对土坝扩建工程的边坡稳定计算方法进行了探讨，以段家峡均质土坝扩建工程为例，按稳定渗流、库水位骤降的非稳定渗流两种情况，并考虑地震等多种荷载组合，对大坝上游坝坡、下游坝坡进行了稳定计算，结果表明，大坝扩建后满足稳定要求。
Methods of dam slope stabilization calculation for earth fill dam expanding project are discussed. Duanjiaxia homogeneous earth fill dam is taken as an example of expanding project, with several kinds of load, including earthquake load being considered, the stabilization calculations of the upriver and downriver dam slopes are carried out according to the following two conditions: steady flow seepage, unsteady flow seepage under the sudden drawdown of reservoir water level. The outcomes show that the expanded earth fill dam be stablized.
