Numerical Simulation of Response of Explosion Ground Shock to Buried Gas Pipeline

In this paper, by using nonlinear dynamical theory and Arbitrary Lagrange Eulerian (ALE) algorithm in LS-DYNA 3D finite element program, a method of numerical simulation is used to study dynamical response of buried gas pipeline underground shock wave of underground explosion. The simulation results shows that it is feasible for the numerical simulation method in this paper to study dynamical response of buried pipelines underground shock waves from explosion. the conclusion in this paper may provide significant reference for the risk evaluation and disaster prevention of buried gas pipeline.
