  • The influence of blasting seismic effect on buried pipes has been an important research hotspot in the field of engineering blasting. Taking two kinds of buried X70 steel pipes with Y-type welds (groove with 2 mm weld reinforcement and groove without weld reinforcement) as examples, the dynamic behaviors of buried X70 steel pipes near the weld zone under blast loads were studied numerically by the finite element software ANSYS/LS-DYNA. The blast loads are formed by detonating 4.473 kg TNT with different blast heights (60.0, 85.0 and 110.0 cm). The results show that when the blast height is 60.0 cm, the pipe with weld reinforcement is greatly affected by stress concentration and that it yields earlier than the pipe without weld reinforcement. When the blast heights are 60.0 cm and 85.0 cm, the ability of the pipe with weld reinforcement to resist deformation is significantly weaker than that of the pipe without weld reinforcement. The interaction between soil and pipe supports the explosion-back surface of the X70 pipe, which can effectively reduce the displacement of the explosion-back surface of the X70 pipe. Under the same conditions, the vibration resistance performance of the X70 pipe with weld reinforcement is weaker than that of pipe without weld reinforcement. Moreover, compared with the weld form, blast height plays an important role in the maximum vibration velocity of the X70 pipe near weld zone.
