土工膜防渗面板在切吉水库整修工程中的应用

Application or geotextile antiseepage facing in rehabilitation of Qieji reservoir

青海省切吉水库大坝整修采用了土工膜面板防渗，基本上解决了防渗、稳定、排水问题．土工膜面板是将土工膜和预制板有机组合，对预制板进行了改进，使其具备空心、连锁、排水的性能，作为防渗土工膜的保护层。具有施工容易、工期短、投资相对较少、安全度高、易修复等优点。

In rehabilitation of Qieji dam,geotextile antiseepage facing was adopted. The problems relating to antiseepage,stability and drainage were basically resolved. The geotextile facing combines geotextile and prefabricated concrete slabs. Frs fabricated concrete slabs were imptoved to have the properties of hollow, chained, and drainage, which were used as protection cover of antiseepage geotextile. This facing has the advantages of easily setting, shorter construction period, relatively lower inwer investment, high safety, and easily repair.
