夹山子水库塑膜防渗施工技术

The Engineering Technique of Construction for Controlling Seepage with Plastic Film in Jiashanzi Reservoir

聚乙烯塑膜用于水库防渗工程，具有造价低廉、施工简便，适应变形能力强、防渗效果好等特点。该项技术首次大面积运用在高水头的夹山子水库已取得了成功。

Polyethylene plastic film used for controlling seepage has many abvantages:less cost,easy to adapt in construction,high ability to adapt deformation,better seepage prevention.This technique was first applied on a large scale in Jiashanzi Reservoir with high water head,and successful results were obtained,which have provided a basic reference for its use to similar areas.
