Study on Shock-Resistant Performance of Buried Pipeline Affected by Different Factors

Abstract

In major city, buried pipelines are more and more important in our life. Its types and layouts are very various, and its surroundings are very complicated. Now, it has been a research hot topic in world earthquake engineering field that how to ensure its safety when extreme earthquake occurred in the future. So, in this paper, based on the ABAQUS software, seismic responses of the soil-pipeline system under different cases are studied, then, the effects of some factors on seismic response of buried pipeline are analyzed, including the vibration direction of earthquake, embedded depth of pipe, pipe diameter, wall thickness of pipe, and tube spacing. Finally, some effect laws are proposed.

A simplified analysis model for determining the seismic response of buried steel pipes at strike-slip fault crossings

“…They studied the Wasatch fault, the largest active fault in Utah to calculate the displacement capacity of the fault. Li et al [19] studied the seismic response of soil-pipeline systems considering directivity effects of earthquake, burial depth, pipe diameter, and wall thickness.…”
