【摘要】 高填方地基的广泛应用,使得对在不同高填方地质情况下,开展研究地震动参数的变化规律有着重要的工程指导意义。根据某机场高填方工程的地基参数,分别概化建立了不同填方厚度、不同压实度、不同厚度原土基的土层计算模型。通过计算得出了场地地震动反应结果。对比研究计算结果,得出了不同高填方地层地质情况下地震动参数的变化特征。为工程设计提供了有效的参数和科学合理的依据。更多还原

【Abstract】 It is very significant for engineering guide to study on earthquake ground motion parameter in filled lands with different thicknesses.According to the foundation parameter of some airports,the site models of different fill thickness,different degrees of compaction,different thicknesses of the original soil bases are build up.Contrasting the research calculation result,the variety characteristic of the earthquake ground motion parameters of thickly-filled lands under different site categories is acquired through actual data.The research result will provides valid parameters and scientifically reasonable basis for the engineering design.更多还原
