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.
