| 摘 要： | 采用弹塑性有限单元法对某电站尾水出口边坡的开挖进行了仿真模拟计算,通过有无锚固条件下边坡的变形、应力状态、塑性区分布,对锚固效果进行了评价.计算结果表明,坡脚部位变形较大,且分布有一定范围的压剪屈服区,对该部位应加强支护.

| Abstract: | The slope-cutting at the exit of the tail-race tunnel of a hydropower station is simulated by elastoplastic FEM computation,through the comparative analysis of deformation and stress of slope and distribution of plastic zone(with or without anchorage),the anchorage effect is evaluated;the computation result shows that the deformation at slope foot is relatively large and a compress-shear yield zone distributes in certain limits,the anchorage work for this area should be strengthened. |
