摘　　要：传统的防渗加固技术以水泥基材料为主要材料,通过大型地质钻机进行钻孔灌浆。水泥基材料在可灌性、流动性、耐久性等性能方面存在不足,施工装备对环境条件要求较高、对工程扰动破坏较大,成本高进度慢。在广泛搜集广西水库资料,调查水库岩溶渗漏问题的基础上,具体分析引发渗漏的形式和原因,针对不同的渗漏类型提出相应的防渗加固技术。介绍了高聚物注浆防渗加固技术及装备,该技术具有对工程扰动较小、施工快捷、经济实用、耐久性好等优点。When traditional anti-seepage reinforcement technology is adopted, cement-based materials are the main materials, and drilling grouting is carried out by use of large geological driller. The cement-based materials have shortcomings in such properties as groutability, fluidity and durability. The construction equipment requires high environmental conditions and may render great interference and damage to the engineering. The construction progress is slow at high cost. The information of reservoirs in Guangxi was collected. Based on the investigation of reservoir karst seepage problem, analysis was made on the types and causes of seepage. Corresponding anti-seepage reinforcement technology was put forward in view of different types of seepage. An introduction was made on the antiseepage reinforcement technology and equipment of high polymer grouting which renders little engineering interference, permits rapid and convenient construction, is economical and practical, and has long durability.
