摘　　要：采用可以描述岩体弹性和弹塑性变形的等效模型—多层结构模型 ,模拟碾压混凝土的应力应变关系 ,据此对龙滩碾压混凝土坝及防渗面板在 3种工况下的受力状态进行了计算 .计算结果表明 ,坝体及坝基内的应力分布合理 ,防渗面板工作状态良好 .An equivalent model,multilaminate framework model, describing both the elastic and elasto plastic behaviours of rock mass, is applied in the stress analyses of roller compacted concrete dams. It can be seen from the stress analyses of Longtan roller compacted concrete dam and its impervious face plate in three different working conditions using this model that the stress distribution in the dam and its foundation is reasonable, and that the impervious face plate works well.
