摘要
在西藏直孔水电站松散砂卵石地层混凝土防渗墙成槽施工中,结合坝基水文地质及工程地质特点,创造性地提出了超前支护成槽方案,通过三维应力模拟和渗透试验,结合现场生产试验,对原方案更进一步完善,在施工中加以应用获得了成功。
Slot completion with advanced support was creatively bought forward during concrete leakage prevention wall making in loose sand and pebble formation for hydropower, considering hydrogeological and geotechnical characteristics of Dam Foundation. The plan was improved after three dimension stress simulation and permeation test, and during actual construction trials. The application results were excellent.
