摘 要:以某管道工程为例,基于场地土层地震反应分析计算,得到管道工程场地地震动峰值调整系数;在与第四代、第五代地震动参数区划图给定调整系数进行对比分析的基础上,确定了管道工程沿线地震动参数区划图的计算原则和方法。最后,计算得到管道工程沿线5 km范围内,不同超越概率水平下的地震动参数区划图。In this paper,taking a pipeline project as an example,based on the analysis and calculation of seismic response of soil layer,the adjustment coefficient of peak ground motion of pipeline engineering site is obtained.The calculation results of the peak adjustment coefficient of the ground motion are compared with the results of the fourth and fifth generation zoning maps.Combined with the characteristics of long distance pipeline engineering,the calculation principle and method of seismic vibration parameter zoning map of pipeline engineering is formed.Finally,the seismic parameter zonation maps of different exceedance probability levels within 5 km along the pipeline are obtained.
