Long-distance oil and gas pipelines cross complicated terrain that different section of the pipeline suffers from different seismic excitation. If a consistent ground motion input is employed to the dynamic response analysis, there will be a big difference with the actual situation. In this paper, multi-support seismic input is considered to make dynamic analysis of long-distance oil and gas pipeline, time history method is used to compare and analyze the dynamic response of a typical long-distance gas and oil pipeline with multi-support and single-support seismic excitation. The dynamic response calculating result tells that these two kinds of seismic input methods have big differences. Therefore, the effect of multi-support seismic excitation should be considered when doing earthquake response analysis of pipes.
