【摘要】 综合波速和计算机模拟计算结果,探讨了在地下水位变化影响下,地基土刚度和密度发生变化后,地震波的传播效应和场地自振特性的变化规律。并根据工程实例分析了基于地下水位变化对场地卓越周期的影响。更多还原

【Abstract】 The rigidity and density changes of foundation soil were studied in this paper,as well as the change rules of earthquake wave spread effect and site dynamic characters,through comprehensive wave velocity test and the computer simulation,in which the ground water level change was taken into consideration.The influence of ground water level on predominant period was investigated in a real project.更多还原
