摘要
卵砾石地层中设置百米深度灌浆帷幕，国内首次，国外也少有。为探索治勒水电站大坝坝基及坝肩防渗设计和施工的技术问题，四川省电力局主持了在冶勒坝址石岸进行的帷幕灌浆试验。本文就已进行第四岩组灌浆情况，分析灌浆的可行性，并对下阶段在第三岩组地层进行试验工作提出一些新的设想。
lt is the first time to place a 100 m depth of grout curtain in pebble and gravel bed in China,and itis a seldom case,atother countries,In order to study the technical problens about impervious foundation andabutments design and construction at Yele hydropower station,Sichuan Power Industry Bureau took charge ofcurtain grouting test which were conducted at right abutment of Yele damsite,Based on grouting of the forth,rock group,the feasibility of grouting is analyzed here,and some new concepts about test of the third rockgroup at next stage are proposed.
