应用随机振动理论分析岩块的起动过程

Analysis of lifting process for a rock block in a plunge pool by use of the theory of random vinbration

本文利用随机振动理论分析了岩块的起动过程，建立了岩块振动过程和脉动上举力之间的统计联系，并在此基础上探讨了岩块的起动条件，导出平衡冲刷时间和冲刷深度发展过程的公式．

y using the theory of random vibration, the process of random vibration for a rock block in a plunge pool is analyzed in details and the statistical relationship between the vibrating process for a rock block and a fluctuating uplift force is obtained. Then, the stability condition for a rock block and the predicting formulae for the equilibrium scouring time and the developmemt of scour depth are derived.
