Based on the analysis of the results of these two cases, the rule of element's σ, at different position is presented, and it shows that the steel panel can effectively reduce the maximal σ, of the element adjacent to the steel panel, and can postpone the arriving time within the simulation time. At the same time, the simulation reveals that the boundary effects don't affect the spalling in the similar structure presented in this paper.

It is the macro effect of accumulative micro fracture in all period of time that spallation failure is induced by reflection of stress wave emerges.

研究结果表明：应力波延续时间和应力幅值对岩石的层裂过程影响较大，不同形状的应力波实际上是在相同时段内应力波具有不同的应力幅值和不同的应力加载速率，不同形状的应力波对介质的作用结果是这些因素同时作用的综合反映；应力波反射诱发层裂过程的发生，是各个时刻不同加载条件下微破裂累积的宏观体现。
