| 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。

| Abstract: | 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. |
