白山水库除险加固工程技术分析

Technical analysis of strengthening and repairing risky reservoir project for Bashan Reservoir

多年以来,白山水库渗漏现象非常严重,虽然经过多次加固处理,但渗漏问题依然没有得到很好的控制。白山水库水文地质条件复杂,进行加固处理并不是件容易的事情。本文根据白山水库现有的水文地质资料,结合目前工程的现状,对地基和坝体进行了渗流和稳定计算,并根据渗流和稳定计算结果分析地基和坝体渗漏的原因,提出切实可行的除险加固优化方案。

Over the years, the seepage phenomenons of Baishan reservoir are very serious. Despite of frequent reinforcements, the leakage still has not been under good control. Due to the complicated hydro-geological conditions of Baishan reservoir, it’s hard to carry out reinforcement measures. According to the existing hydro-geological data and combing with the present status of the project, the paper calculates seepage and stability of both the foundation and body of the dam, and analyses the cause of the seepage. Based on the results of calcu- lation, feasible reinforcement optimum proposal have been put forward.
