| 摘 要： | 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。对高水头、大流量作用下,反拱圈弹性单底板块的振动特性进行了试验研究,给出底板块沿流程各振动区域的划分界限,得到拱圈单底板块振动特征值沿流程分布规律及时域和频域特性,为反拱水垫塘失稳机理的研究提供了科学依据。 |
| 关 键 词： | 反拱水垫塘 单底板块 振动 失稳 |

| Abstract: | 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. Experimental research on the vibration of single elastic slab set in the arch ring is carried out under the action of high water head and large flow.Slab vibration divisions' boundary lines along the water flow are determined.Laws of vibration distribution along water flow,in time zone and frequency one are established.The results provide the scientific basis for the study of stability failure of inverted arch plunge pool. |
| Keywords: | inverted arch plunge pool slab vibration stability failure |
