寒区水电站高面板堆石坝沉降特性研究

Studies on Settlement Characteristics of a High Concrete Face Rockfill Dam in Cold Region

摘要: 为了研究寒区高面板堆石坝的沉降变形特性，建立了堆石坝沉降与库水位、环境温度和时效之间的非线性关系模型，分析认为坝体沉降已基本稳定，与同类型的面板堆石坝相比沉降较大。同时分析了坝体内部测点沉降变幅较大的原因，认为主要与水管内水温的变化有关。

Abstract: In order to study the settlement characteristics of high concrete face rockfill dam in cold region, the mathematical models of the dam deformations versus the water level, the environmental temperature and the time-effect are proposed. It is concluded that the dam settlement is basically stable, and the settlement is larger than that of the same type of faced rockfill dams. Meanwhile, the reason for large settlement variation of the monitoring points inside the dam body is analyzed, which is mainly related to the change of water temperature in the water pipe.
