重力坝静力计算概念坝体上游防渗层及其下游水势多用沉陷缝与溢流重力坝隔开,所以后者的静力计算应单独进行。在这种情形中,对混凝土坝体,施着最后的下列力量(参看图一):形成水平水压力的 Q 及力臂 y;由上向下的坝体自重垂直力
The concept of gravity calculation of gravity dam The upstream seepage prevention layer and its downstream water potential multi-purpose subsidence joint are separated from the overflow gravity dam, so the latter’s static calculation should be carried out separately. In this case, apply the following last force (see Figure 1) to the concrete dam: Q and arm y that form the horizontal water pressure; vertical weight from the dam body up and down
