By making theoretical analysis of vibration of a single slab set in the inverted arch ring,four processes about stability failure of slab,that is free vibration,locking,sleeking and distortion are proposed on the condition that water sealing was damaged and anchor-hold was out of action.
对反拱水垫塘单底板块振动特性进行了理论分析,提出了在止水破坏、锚固力失效后,拱圈单底板块失稳分为自由振动、锁定、滑动变形及失稳破坏4个过程。
