龙滩水电站主体工程建设共分为５个标。其施工导流选用隧洞导流方式，围堰采用碾压混凝土过水围堰，挡水标准为１０年一遇，挡水流量１４７００ｍ３／ｓ，该围堰拟由承包商设计，挡水标准可适当降低。经方案比选，施工总进度采用７年半发电方案。大坝混凝土量约６０１万ｍ３，主要浇筑期４１个月，选用进口高速皮带机运输上坝，仓面塔式布料机浇筑为主，缆式起重机为辅的混凝土运输浇筑方案。
The main project construction of Longtan Hydropower Station is divided into 5 standard. The construction diversion adopts the tunnel diversion method, and the cofferdam adopts the RCC cofferdam. The water retaining standard is 10 years and the water retaining flow is 14700m3 / s. The cofferdam is intended to be designed by the contractor and the water blocking standard Appropriate to reduce. After the program comparison, the total construction progress using seven and a half power generation program. Dam concrete volume of about 601 million m3, the main pouring period of 41 months, the choice of imports of high-speed belt conveyor dam, warehouse surface-based placement of concrete pouring machine, cable crane supplemented concrete transportation and pouring program.
