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.
採用可以描述巖體彈性和彈塑性變形的等效模型&多層結構模型,模擬碾壓混凝土的應力應變關繫,據此對龍灘碾壓混凝土壩及防滲麵闆在3種工況下的受力狀態進行瞭計算.計算結果錶明,壩體及壩基內的應力分佈閤理,防滲麵闆工作狀態良好.

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.
