摘要
辉发城水库除险加固工程坝基为二元结构,坝后坡脚的地下水位高出地表0.45m,表层淤泥质粘土层存在渗透稳定问题。本文在除险加固勘察基础上,利用规范法对坝后淤泥质粘土进行渗透稳定计算,并提出了地基处理措施,对类似工程具有借鉴意义。
The dam foundation of Huifacheng reservoir reinforcement project is belong to dual structure,the underground water level behind the dam toe is 0.45m above the surface,the surface stratum of silt clay has issue of infiltration of stability.In this paper,the permeability and stability calculation of silt clay behind the dam with standardized method based on the reinforcement survey is introduced and foundation treatment measures which can be referenced by the similar projects is put forward.
