摘　　要：通过对设计水头为３９．５ｍ的预应力混凝土蜗壳进行三维仿真数值模拟，计算了不同工况不同锚索初始张拉力的应力分布状况。结果表明，锚索初始张拉力的大小对混凝土蜗壳及座环的应力状况有重要影响。By 3D numerical imitation for the prestressed concrete snail shell under the designed water head of 39.5m, the stress distribution of the anchor's initial tensile force is calculated in different workable situations. The results show that the values of the initial tensile force have an important effect on the stress situations of concrete snail shell and ring base.
