摘要
对昆明两个不同土层结构性质的场地模型输入同一个人工合成近震大震地震波的基岩地震动,得到了两个场地土层反应的地表地震动加速度时程及其反应谱,对比分析了它们的特征和差别,探讨了这两种不同性质土层在基底遭受近震大震时场地地震反应对地面运动特征的影响及其意义.
The same synthetic seismic wave of bedrock ground motion is input to the site model of two different soil layers in Kunming area.The ground motion acceleration time history and its response spectrum of soil reaction at two sites are obtained.Their characteristics and differences are compared and analyzed.The effects of site seismic response on ground motion features of the two different soil layers subjected to near large earthquake and related significances are discussed.
