龙滩大坝应力和稳定计算分析研究

Research on Stress and Stability Calculating Analysis of Longtan Roller Compacted Concrete Gravity Dam

通过有限元计算对龙滩碾压混凝土重力坝的应力和稳定进行了研究。分别对溢流坝段、挡水坝段进行了静力和动力分析，其中引入节理单元和低强度单元考虑混凝土碾压层之间的稳定与弹塑性问题。

In this paper the stress and stability problems of Longtan Roller Compacted Concrecte (RCC) gravity dam are researched by means of finite element method.For the two sorts of dam sections the regularly static and dyramic responding have been analysed.Aften using joint elements and low intensity elements to study the stability and elastic plastic problems between two different layers of RCC dam,the seismic safety of Longtan RCC gravity dam can be evaluated more reasonable.
