摘　　要：河床深厚覆盖层是水利水电工程建设中经常遇到的主要工程地质问题之一,河口村水库坝基河床覆盖层最厚处达41.87 m,岩性复杂,地质结构极不均匀。通过勘察、试验等研究工作,基本查明了坝基河床覆盖层不同岩性组的分布情况及其工程地质特性,并分析了对工程的影响,为河口村水库大坝设计提供了科学的依据。The thick overburden in Hekoucun dam foundation is one of major engineering geological problems in the construction of the dam.The overburden is 41.87 m high at most,and is very complex in composition and extremely uneven in geological structure.The distribution and engineering geological characteristics are basically known by investigation,test and so on,and its impact upon the reservoir is analyzed,therefore providing scientific basis for the design of reservoir.
