摘　　要：本文将光子晶体的概念应用于土层结构设计,并利用传输矩阵法计算了p波在土层结构中的传播特性。结果表明,这种土层结构可以全部反射特定频率范围内入射的p波,从而可以减少p波对地上建筑的破坏。此外,还考察了土层的物理特性对反射频带的影响。The concept of photonic crystals was applied to design the layered soil structure that can reflect p waves. The propagating behaviors of p waves across the structure were studied by using transfer matrix method. The results show that the structure can totally reflect p waves. The physical properties of the layers on the width of the band gap were also studied.

关 键 词：土层结构 P波 能带隙
