Study on the Key Technologies of Seismic Ground Motion Parameter Zoning of Pipeline

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.
