摘要 采用波函数展开法 ,给出了平面P波入射下半空间中洞室群对地面运动影响问题的一个级数解答 .数值结果表明 ,地下洞室群对附近地面运动具有显著的放大作用 .建议地铁等地下工程在规划和设计时 ,考虑工程建设后对沿线地面运动的影响 . A series solution for surface motion amplification due to underground group cavities for incident plane P waves is derived by Fourier Bessel series expansion method. It is shown that underground group cavities significantly amplify the surface ground motion nearby. It is suggested that the effect of subways on ground motion should be considered when the subways are planned and designed.
