组合式沉井（箱）群在水电站设计中的应用

Applying Combined Caisson Group to the Design of Hydropower Station

在江河湖泊的沿岸地带修建水电工程中的站房建筑物常常遇到深厚软弱地基，同时还受到周边环境的限制，致使工程实施困难，耗费较大。针对这个问题，根据工程实践提出了使用组合式沉井（箱）群技术的办法，并介绍了其技术特点。

A deep soft-weak foundation will be met with frequently when constructing power house of hydropower project at the shore of river and lake.Meanwhile because of the restriction of surroundings also,so that its construction implement will be difficult and its construction cost will be more expensive.To counter this problem,based on engineering practice a techanical method of using combined caisson group is suggested,and its techanical characters are introdued also in this paper.
