Abstract：
Analytical research was conducted systematically on the battle-induced structure damage based on the subway station target, and combined with the common ways to strike the urban subway station structure with conventional weapons, a simple analysis of target characteristics was carried out and a calculation and assessment flow was established for the battle damage to the subway station structure. Based on the establishment of the criteria for damage, a more detailed analysis of battle-induced structure damage was conducted, key parameters, such as radius of collapse, peak value of equivalent uniformly distributed dynamic load at different areas, vibration acceleration and vibration time, were calculated, and calculation was illustrated according to the specific examples of penetration and explosion above the subway station. From the results of calculation, it can be seen that the established method and flow of calculation and assessment of battle-induced structure damage can rapidly and accurately evaluate the damage to subway stations and also provide a useful reference for research into the protection of subway stations and emergency repair and rescue after battle-induced structure damage.
