摘要
比较了粘弹性边界、粘性边界和固定边界条件的精度.根据不同边界条件,采用振动方法和波动方法,进行了在地震荷载作用下隧道结构的反应分析,分析了无限地基对计算结果的影响以及在地震荷载作用下隧道衬砌的薄弱部位.
The computing precision of three type conditions such as viscous-spring boundary, viscous boundary and fixed boundary is compared. Based on various boundary conditions, the seismic response studies of a tunnel are executed by using vibration-method and wave-method respectively. The influence of infinite foundation soil to the earthquake responses of the tunnel is researched and the weak parts in liner are determined.
