| 摘 要： | 本文用动态光弹性探讨了地表爆炸产生的应力波与地下结构物相互作用的机理,根据等差条纹分布分析了P波、S波、von Schmidt波及R波与结构物基础的相互作用过程。研究表明R波是对地下结构物危害最大的波。可以采取防护措施来反射和消耗R波的能量。

| Abstract: | The mechanism of the interaction of blasting stress waves generated on the ground surface with a underground structure was investigated by dynamic photo-elasticity in the present paper. The process of the interaction of P-wave, S-wave, von Schmidt wave and R-wave with the base of a structure were analysed according to the recorded isochromatic fringe patterns. The analysed results indicated that R-wave is the most dangerous wave for the safety of the underground structures.The protection can be adopted in order to reflect and consume the energy in R-wave. |
