| 摘 要： | 从碾压泥凝土坝的渗透特性出发，采用裂隙流模型分析了碾压混凝土坝（缝）面渗流问题，进而提出碾压混凝土坝层（缝）面渗流对坝体应力影响的作用机理：渗流向层（缝）壁面施加垂直于壁面的法向渗透压力及平行于壁面的切向拖 Ye 力，并采用有限元数值方法具体分析了碾压混凝土坝工程实例层（ 缝）面渗流对坝体应力的定量影响。

| Abstract: | Based on the characteristic of seepage through layered roller compacted concrete dam(RCCD), two kinds of force applied on the layered wall are studied, which include the normal seepage pressure and the tangent hauling force. The equivalent node force of joint element is deduced under the three-dimensional condition. An engineering example is also given to indicate the effect of seepage in layered RCCD on the stress of the dam. |
