Value Analysis of Seismic Peak Ground Acceleration in Different Design Reference Period for Moscow-Kazan High-speed Railway

为莫喀高铁采用不同抗震设防标准提供相应动参数,在分析莫喀高铁地质地震构造和地震特征基础上,通过有关地震参数的相关性,计算不同设计基准期内不同超越概率对应的重现期、地震烈度、地震动峰值加速度,对比分析计算结果,地震动峰值加速度按照俄罗斯标准比中国大1. 32倍;给出任意基准期内不同超越概率下地震动参数的计算方法。

In order to ofier relevant seismic dynamic parameters for the earthquake-resistance design of Moscow-Kazan high-speed railway based on different standard, this paper calculates the return period, seismic intensity and peak ground acceleration （PGA） corresponding to different exceeding probability in different design reference period based on the analysis of geological seismic structure, seismic characteristics and seismic parameters relevance. The comparing analysis of different calculation results indicates that PGA in Russia is 1.32 times larger than that in China. Finally the calculation method of design seismic parameters on different exceeding probability in any design reference period is put forward.
