摘要
云南省小型水库有5 223座,其中病险土石坝水库约占40%,普遍存在大坝渗漏问题。目前大坝防渗处理技术措施较多,如何因地制宜地选择防渗处理方案以满足除险加固工程的功能性、可实施性、经济性、环境和安全性的要求,是建设各方必须重视的问题。本文分析了大坝渗漏的类型及成因,并根据云南省小型水库的实际情况和各类防渗处理技术的特点,提出了有针对性的优选方案和施工中应注意的问题,为小型水库的防渗加固处理提供参考和借鉴。
There are 5 223 small-sized reservoirs in Yunnan province while 40% of them are diseased, and seepage exists widely. Thus, seepage control is a great part of dam rehabilitation and the anti-seepage treatment measures are of great importance. Cause reasons and types of seepage were analysed in this paper. What＇s more, the optimized measures and issues need attention in construction were advanced, for reference to similar rehabilitation projects.
