摘　　要：诸多闸坝工程直接坐落在砂卵石地层上,由于基础未处理或处理未达到理想效果,运行过程中出现坝基础渗漏、坝身沉降、开裂,严重时出现管涌、垮坝等事故。砂卵石基础出现此类情况后,施工处理难度大,往往需要采用综合防渗加固技术,才能达到预期目的。以广西某闸坝式水电站为例,介绍砂卵石基础内综合防渗加固施工技术的应用,供类似工程参考。Many dam projects are located directly on the sand and cobble stratum. Due to the basis of untreated or treated not reached the desired effect, operations appear dam foundation seepage and settlement of dam body, dam body crack. After the occurrence of such cases, the construction process is difficult, often need to use the comprehensive reinforcement technology,in order to achieve the desired objectives. Taking a dam type hydropower station in Guangxi as an example, this paper introduces the application of the construction technology of the comprehensive seepage prevention and reinforcement ,which provides reference for similar projects.
