前言对于要求按动力设计建筑物的基础、桥墩等的土壤工程师来说,土的抵抗力和基础位移之间的关系是极端重要的。一般假定土层的反作用力对基础块体的位移是成比例的,但真实的动力反作用模型并不是已知的。动力特性的流变模型至今还没有找到,尽管已有了许多实验和理论的研究(Barkan,1962;Goto,1952;IShimoto,1937)。所涉及的一个主要困难是土的反作用力对于变形的依赖性;因此,在不同层内需要研究变形- Foreword For soil engineers who require dynamic design of building foundations, piers, etc., the relationship between soil resistance and foundation displacement is extremely important. It is generally assumed that the reaction force of the soil layer is proportional to the displacement of the basic block, but the real dynamic reaction model is not known. The rheological model of dynamic properties has not yet been found, although there have been many experimental and theoretical studies (Barkan, 1962; Goto, 1952; Ishimoto, 1937). One of the major difficulties involved is the dependence of the soil’s reaction forces on deformation; therefore, the deformation needs to be studied in different layers -
