本文利用随机振动理论详细地分析了高坝下游水垫塘底板块的失稳破坏机理和板块的起动过程,建立了板块振动过程和脉动上举力之间的统计联系,并在此基础上导出了板块的动态稳定性条件,为板块的设计提供了科学依据.
In this paper, the random vibration theory is used to analyze in detail the instability and failure mechanism of the plunge pool and the starting process of the plunge pool in the downstream of the high dam. The statistical relation between the plate vibration process and the pulsating upper lifting force is established. Based on this, The dynamic stability of the plate conditions for the plate provides a scientific basis for the design.
