摘要

研究场地在地震作用下的反应,是场地抗震评价的重要任务之一.文中采用基于波传播理论的直接刚度法,分析了刚度增长场地和含有软弱土层的层状场地在平面外SH地震波入射下的动力响应.得出的结论可在一定程度上提前预估自由场地的反应.
To study the response of a free-field under earthquake is one of the important tasks of evaluating the field's capability of resisting earthquake.The dynamic responses of a common field and the fields including the soft intercalations are analyzed by means of the method assembling the dynamic-stiffness matrices and load vectors of the individual,which based on the theory of wave transmitting.The conclusion can help forecast the response of a free-field under earthquake to a certain extent.
