摘　　要：利用有限元法对可能导致天荒坪电站上水库西岸副坝7号廊道底板开裂的各种原因进行了分析研究,结果表明廊道两侧边墙的超挖回填材料软弱是导致7号廊道底板开裂的主要原因,为加固方案的设计提供了可靠的依据。In the west auxiliary dam of the upper reservoir in Tianhuangping Hydropower Station,cracks are observed in the floor of the No. 7 gallery. A finite element analysis is then carried out on possible reasons of such cracking. It shows that the soft backfill soil behind side walls of the gallery could be the key reason,which provides useful insight to the design of reinforcement.
