拔贡水电站改扩建工程纵向混凝土围堰设计

摘要

The paper makes a brief intr oduction to the structure type design,the stability and stress calculations on the longitudinal concrete cofferdam of Bagong Hydropower Extension Project. A gravity-type C15 plain concrete cof-ferdam is adopted for the project due to its low water-retaining head,which not only reduces the project cost,but also facilitates the construction and speeds up construction progress,which is conductive to an earlier power generation of the project.%　　文章简要介绍了拔贡水电站改扩建工程纵向混凝土围堰的结构型式设计和稳定、应力计算。因纵向混凝土围堰挡水水头不高，因此围堰采用重力式C15素混凝土围堰，方便施工，节省投资，加快工程进度，有利于本工程尽早蓄水发电。
