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。对大坝的抗震安全性作了评估
The stress and stability of Longtan RCC gravity dam are studied by finite element method. The static and dynamic analysis of the overflow dam section and the dam section are respectively carried out. The introduction of the joint unit and the low strength unit consider the stability and elasto-plasticity of the concrete layer. The seismic safety of the dam was evaluated
