Abstract
- Long-distance buried pipelines inescapably go through seismic fracture zones which makes the buried pipelines be easily influenced by the diastrophism. A strong and resilient pipe can withstand a certain degree of seismic oscillation. However, it is really difficult for buried pipelines to resist the permanent ground displacement caused by faulting and surface damage. Most of the existing studies only focus on the two-phase contact between pipeline and soil, and the mechanical behavior of the cross-fault pipeline under transportation condition has not been studied. In this article, ADINA finite element software is used to establish a pipe-soil-fluid three-phase coupling model based on fluid–structure interaction (FSI), and the influence of the parameters of pipe, fluid and fault on the mechanical properties of cross-fault buried gas pipeline is studied. The model considering the effect of fluid–structure interaction can effectively simulate the mechanical response of pipelines in the actual working condition. The work presented in this article can provide a reference for the design and safety of cross-fault buried pipeline conveying fluid.
