摘要
Abstract
Based on the Jinchuan Hydropower Project on the Dadu River,foundation treatment tests and scheme comparison studies were conducted under complex geological conditions.Riverbed overburden resurveys,on-site dynamic compaction tests,and consolidation grouting tests were conducted.The physical and mechanical properties of the riverbed overburden and the distribution characteristics of various rock formations at the dam site were determined.The reinforcement effects of different overburden treatment schemes were evaluated,and the final overburden reinforcement measures and construction techniques were determined.These solutions ad-dressed engineering challenges such as deformation control and coordination between the dam foundation and the dam body,and uneven settlement of the overburden in the toe plate and connecting plate areas.A compre-hensive dam foundation reinforcement scheme was proposed and implemented,including excavation and re-placement of the shallow sand layer on the foundation surface,combined with dynamic compaction and consoli-dation grouting,and supplemented by vibratory rolling of the dam foundation.This scheme achieved satisfacto-ry results.关键词
