摘要
根据柳沟水库的地质勘察资料,结合柳沟水库除险加固工程中坝基存在渗透不稳定破坏的严重问题,通过对坝体坝基进行渗透稳定分析计算,提出采用多头小直径深层搅拌桩截渗墙对坝基防渗处理,增强坝基的渗透稳定性,确保水库的安全。
Based on the geological exploration data, combining with existing serious problems of seepage insta- bility in dam foundation of Liugou reservoir , in construction of strengthening and eliminating dangers, through the calculation of seepage stability of the dam body and foundation, the multi-head and diminutive diameter mixing pile cut-off wall is used to anti-seepage treatment for the dam foundation which could enhance the seep- age stability of the dam foundation and ensure the safety of the reservoir.
