摘　　要：榆树沟贮灰场已加高至五级子坝,为筑第六级子坝并保证灰场下游居民的安全,根据现有监测资料及室内试验数据,基于Geo-Studio分析软件,对贮灰坝进行渗流、应力应变以及静动力稳定性计算,判别灰场运行的安全性及子坝加高的可行性。综合评价贮灰坝稳定满足要求,可进行六级子坝加高,建议加强变形监测。The ash dam of Yushugou has been raised to the fifth stage, to ensure the safety of the downtown residents and build the sixth stage. A coupling analysis is made of seepage field and stress field of the slope stability by software Geo-Studio. The operation safety and the feasibility of sixth sub-dam is evaluated according to the existing monitoring data and laboratory test data. The stabili- ty meets the code and can heighten the sixth sub-dam. Suggestions are given on how to strengthen the deformation monitoring.
