摘　　要：根据现场被冲击物的实际量测破坏形态,利用直接反演分析原理,以数值仿真分析所得叠层岩板破坏规律与现场实际岩板破坏形态的相似度最大为追求目标,进行识别反演层状岩板冲击载荷的数值范围和动抗拉强度估计值.文中分析思路对初始信息及量测信息溃乏的工程问题的反演分析尤为适用.According to the in-situ measurement of damage shape of impacted object and the theory of direct back analysis, the magnitude of the impact load and the dynamic tensile strength for laminar rock plank are identified by taking the similitude-degree between the measured damage shape and the numerical simulated shape as the target function. The analysis method is effective for some ancient architectures, especially when the initial information and measurement data, are scare.
