Abstract

Buried gas pipelines in karst area is inevitably affected by the geotechnical activities, which is difficult to resist the permanent ground displacement caused by soil dislocation and surface damage. In this paper, ABAQUS finite element software has been used to establish a pipe-soil nonlinear coupling model based on element birth and death technique. The influence rules of various sensitive factors on the stress response of gas pipelines are studied. The work presented in this paper can provide a reference for the design and safety of PE gas pipeline crossing the karst area.

基于单元生灭技术的岩溶地区Pe-天然气管道力学响应影响因素研究

岩溶地区埋地输气管道不可避免地受到岩土活动的影响，难以抵抗土体错位和地表破坏引起的永久性地面位移。本文利用ABAQUS有限元软件建立了基于单元生灭技术的管-土非线性耦合模型。研究了各种敏感因素对输气管道应力响应的影响规律。本文的工作可为穿越喀斯特地区的PE输气管道的设计和安全提供参考。

期刊介绍： The Journal of Pressure Vessel Technology is the premier publication for the highest-quality research and interpretive reports on the design, analysis, materials, fabrication, construction, inspection, operation, and failure prevention of pressure vessels, piping, pipelines, power and heating boilers, heat exchangers, reaction vessels, pumps, valves, and other pressure and temperature-bearing components, as well as the nondestructive evaluation of critical components in mechanical engineering applications. Not only does the Journal cover all topics dealing with the design and analysis of pressure vessels, piping, and components, but it also contains discussions of their related codes and standards. Applicable pressure technology areas of interest include: Dynamic and seismic analysis; Equipment qualification; Fabrication; Welding processes and integrity; Operation of vessels and piping; Fatigue and fracture prediction; Finite and boundary element methods; Fluid-structure interaction; High pressure engineering; Elevated temperature analysis and design; Inelastic analysis; Life extension; Lifeline earthquake engineering; PVP materials and their property databases; NDE; safety and reliability; Verification and qualification of software.
