摘　　要：稳定性分析是堤防、土石坝等以稳定性为控制条件的工程设计的一项重要工作 ,在软土地区尤其如此。由于软基堤坝稳定问题主要出现在施工期间 ,特别对于进行地基处理过的软基。本文结合工程实际 ,通过对湖相沉积软土上分级加载的堆石坝进行稳定性分析 ,指导了工程安全施工 ,收到了一定的效果。The stability analysis is a key job of earth banks and dykes,of which stability is regarded as the control condition of engineering design, particularly in the soft land area. The stability problems of dams appear primarily in the period of construction, especially the foundation that have been treated. This paper discusses the engineering construct which achieves some effect through combining engineering practical situation with the study on stability analysis of the dam that is under multi-stage preloading in some sedimentation areas of lake facies.
