| 摘 要： | 反拱形底板的稳定主要靠拱座和锚固钢筋维持．利用接触问题处理底板与基岩、拱端与拱座、边坡与基岩的接缝，用杆单元模拟底板与基岩之间的锚固钢筋，对长潭岗反拱形水垫塘衬砌结构进行了非线性静动力计算，得出了水垫塘衬砌结构在接触状态下的位移、应力和拱端推力等．该计算方法对其他大型水垫塘设计计算可提供一些参考。

| Abstract: | Stability of the reverse-arch-shaped floor is largely dependent on the arch supports and their anchor bars. Rod elements were used to simulate the anchor bars between the floor and foundation rock,suppose we make use of the problem of contacting to treat the joints floor-foundation rock,arch abutment-arch support and slope-bed rock. The non-linear static and dynamic calculations of lining structure for the water cushion pond have shown the deflections,stresses and pushing forces of the pond lining structure in a contact state. These calculations can provide basic reference data for other large-size water cushion pond designs. |
