∶用Duncan-Chang E-B模型模拟堆石体，接触面单元模拟面板与垫层之间的接触，面板竖缝和周边缝用分离缝模拟，对老挝南涧河面板堆石坝方案进行三维有限元变形应力分析，得到了堆石体、面板的位移应力及分布规律，分析了面板竖缝和周边缝的变形。计算结果较为全面地反映了坝体的实际工作状况，为南涧河面板堆石坝的优化设计提供了依据。
∶用Duncan-Chang E-B模型模擬堆石體，接觸麵單元模擬麵闆與墊層之間的接觸，麵闆豎縫和週邊縫用分離縫模擬，對老撾南澗河麵闆堆石壩方案進行三維有限元變形應力分析，得到瞭堆石體、麵闆的位移應力及分佈規律，分析瞭麵闆豎縫和週邊縫的變形。計算結果較為全麵地反映瞭壩體的實際工作狀況，為南澗河麵闆堆石壩的優化設計提供瞭依據。

The displacements and stresses of rockfill dam and face slab and their distributions are obtained, and the deformations of face slab joints and peripheral joints are analyzed through 3D FEM deformation-stress analysis of Laos Nam Chiane concrete-faced rockfill dam scheme by simulating the rockfill dam using of Duncan-Chang E-B model, simulating the contact face between face slab and cushion layer using of contact face element, and simulating face slab joints and peripheral joints using of separation joints. The results generally show the actual working condi-tions of the rockfill dam and provide important references for optimal design of Nam Chiane concrete-faced rockfill dam in Laos.
