Abstract EN
According to the advantages of high tensile resistance and high shear strength of composite steel plate, a new antiexplosion protection method of composite steel plate lining structure is put forward.
The numerical model of explosion impact of subway tunnel with composite steel plate lining structure was established by dynamic analysis software.
The transient dynamic response of lining structure with the composite steel plate was simulated when explosion occurred.
The research results show that the influence of explosive quantity on each point of composite steel plate lining structure is different and the change of acceleration near the centre of the detonation source is generally greater than the multiple of the increase of explosive quantity.
The increase of velocity and displacement is basically consistent with the quantity of explosive.
The influence of axial stress on the lining structure is the least, and the influence of the lining structure is greater in the y-direction than in the x-direction.
The research results can provide the plan and basis for the emergency response of the subway tunnel.
