摘要
龙滩水电站200 m级碾压混凝土重力坝渗控系统是大坝设计和施工的重点。针对工程实际情况,详细阐述了龙滩碾压混凝土重力坝采用全断面碾压混凝土,坝面采用变态混凝土与二级配碾压混凝土组合防渗形式方案的设计、施工、缺陷处理,结果表明,大坝渗流控制系统的实施效果较好,层面间扬压力较小。
The seepage control system plays a key role in design and construction of 200m RCC gravity dam at Longtan hydropower station. In light of the practical conditions of the project, the dam is built into a whole profile RCC gravity type. A seepage control proposal combining abnormal concrete and two-graded RCC is designed for dam profile, and is applied to engineering practice and defect treatment. Such seepage control system is proved to have good effect with relatively small uplift pressure between layers.
