安康水电站的岩石比较软弱,风化层厚度达50～60米,经多次构造运动,地层褶曲,断裂发育,特别是由坝基下平缓断层所引起的大坝抗滑稳定问题,是本工程的主要工程地质问题。通过大量勘探特别是施工阶段的补充勘探工作,取得了大量实际资料,并对这一问题进行了研究。本文着重介绍研究的综合成果,同时对大坝抗滑稳定的工程地质条件作一简要分析。 The rock of Ankang Hydropower Station is relatively weak, and the thickness of weathering layer reaches 50-60 meters. After several tectonic movements, strata folds and faults, especially the stability of dams which are caused by the gentle subduction of dams, it is the main project of this project Engineering geological problems. Through a large number of exploration, especially in the construction phase of the supplementary exploration work, a great deal of actual data has been obtained and the problem has been studied. This article focuses on the comprehensive results of the study, and at the same time makes a brief analysis of the engineering geological conditions of the dam against skidding and stability.
