摘要
针对矩形沙河渡槽不同水位在横向激励下的时程响应,计算横向应力和纵向应力,分析其分布规律;计算渡槽跨中和1/4断面的水平位移,结果两者数值相当,均较小.从而得出矩形沙河渡槽在地震作用下具有足够的强度和刚度.
Lateral stress and longitudinal stress are calculated in the time response of lateral stimulation at different water level of rectangle Shahe aqueduct,the regularities of distribution is analyzed;horizontal displacements of midspan and 1/4 cross-section are calculated,two values are both small and equivalence.Then the result is got that rectangle Shahe aqueduct possess adequate strength and stiffness for earthquake effect.
