重力坝下游面浅槽式压力管道的抗震计算分析

Calculation and Analysis on Seismic Resistance of Groove Type Penstock in the Downstream of Gravity Dams

通过对重力坝下游面浅槽式压力管道的动力分析，分别研究了该结构位于刚性和弹性基础上的动力响应规律．给出了重力坝和下游面压力管道各典型部位在地震荷载作用下的动位移及动应力，为该类型大坝设计提供了可靠的参考依据．

By means of dynamic analysis on groove type penstock in the downstream surfaceof gravity dams, the laws of dynamic response of this structure on the basis of rigidity andelasticity are respectively studied. In the meantime, the dynamic displacements and thedynamic stresses under seismicloading are given for each typical part of such like penstock.These offer the realiable reference for design of the such type dams.
