混凝土面板砂砾石坝垫层料过渡料渗流及渗透稳定性试验研究

Study on bedding and transition materials' seepage and permeation stability tests for Geiquan concrete face sand/gravel dam

近年来砂砾料以其低压缩性、易压实、造价低等一系列优点 ,日益为高坝建设所利用。然而砂砾料的渗透及渗透稳定性一直是面板坝建设所关注的问题 ,它直接关系到大坝的安危。介绍了黑泉水库垫层料、过渡料的试验研究成果直接应用于工程建设。

In recent years, sand/gravel material is increasingly used for high dam construction due to its low compressibility, easy compaction and low cost, However, its seepage and permeation stability has been a major concern for concrete face rockfill dams, as it is directly touch the dam safety. The paper presents the test results of bedding and transition materials for the Heiquan dam, which can be directly used for dam construction.
