摘　　要：本文采用一维波动理论对地震波在不均质地基中传播时产生的空间变动进行分析,得出具有不同振幅变化倍数和相位的地面运动,利用此结果对质量分布均匀、大跨度单层球面网壳进行多点输入的地震反应分析。同时为突出场地土的不均质性,本文针对场地效果(site-response)产生的空间变动。In this paper, by applying one dimensional wave theory, spatial variability caused by irregular ground is analyzed. Then surface ground motion with different ratio of amplitude and phase difference is found. Based on these results, the dynamic response analysis of the dome is carried out with the input of different ground motions at multi supports. At the same time, the seismic response of the dome is investigated considering the spatial variability caused by site response effect in order to emphasis the effect or irregular ground. [
