摘要
本文比较了新旧抗震规范的差异,对土石坝动力分析的几个关键问题如阻尼、地震波的输入、地震影响系数、土的动力本构模型、液化机理进行了探讨,为大坝抗震设计和动力分析提供指导意义。
In this paper, the difference between the old and new seismic code is compared. The several key issues of the dynamic analysis of the earth and rock dam such as the damping, the input of seismic waves, earthquake coefficient, dynamic constitutive model of the earth, liquefied mechanism were discussed, which provides the reference for the dam design against the earthquake.
