    Abstract：By using the dynamic finite element program LS-DYNA and the coupling method Euler-Lagrange and taking 75 g columnar and 200 g blocky TNT explosive as explosion resource respectively, 3D numerical simulation is conducted on nonlinear dynamic response process of buried pipeline under the action of explosion loading, described are dynamic responses of buried pipeline in different burial depths and wall thickness conditions and comparison is conducted with experimental results. Study results provide important reference for explosion-resistant property analysis and safety assessment of oil and gas pipeline safety.
