| 摘 要： | 研究了平面SV波入射下半空间中洞室群对地面运动的影响 ,数值结果表明 ,地下洞室群对沿线地面运动具有显著的放大作用 ,该放大作用可达无洞室情况的 1 5～ 8 8倍以上 ,地表位移幅值的最大值出现在波 45°入射情况并位于与入射波相对的区域。建议在地铁等地下工程的规划和设计时考虑工程建设后对沿线设计地震动的影响

| Abstract: | This paper studies the effect of underground group cavities in half-space on the surface ground motion under incident plane SV waves.The numerical results show that the group cavities can greatly amplify the surface ground motion, and the amplification can be 1 5 to 8 8 times of that without cavities, and the maximal displacement amplitude appears at incident angle of 45 degree and is located opposite to the incident waves. It is suggested that the effect of underground group cavities on design ground motion be taken into consideration when the group cavities are planned and designed. |
