Influence Study of Frost Heaving Conditions on Seismic Performance of Buried Pipelines

The frozen soils are distributed extensively in China. The east-west and the northern pipelines are mostly buried in such regions. China is also an earthquake-prone country. Once seismic conditions are considered in the frozen regions, the performance of pipelines will face many problems. The finite element method was used to analyze the seismic responses of pipelines in different frost heaving conditions. The time-history responses of displacement and acceleration of pipelines in different frost heaving conditions were obtained, and the results were also compared and analyzed. The results indicate that the different conditions of frozen soils should be considered in seismic responses of pipelines to make the pipelines safe and economical, and more attention should be paid to the design and study of pipelines in frozen soils.
