提出了一种简单的计算任意形状刚性基础在合理深度和均匀土层中的静、动力摇摆刚度的方法。这种方法是建立在对问题物理的更好理解的基础上的，得到了使用边界元方法的广泛的严格参数研究的结果的证实，并包括了文献中提供的分析和数值结果。建立了适用于饱和和非饱和土体、不同底垫形状、不同埋入深度和竖向侧壁与周围土体接触类型的解析表达式和无量纲图。一个数值例子说明了该方法的适用性，而另一篇论文(Fotopoulou et al.1989)提出了一种确定埋置基础辐射阻尼的简单方法。
A simple procedure to compute the static and dynamic rocking stiffness of arbitrarily shaped rigid foundations embedded in a reasonably deep and homogeneous soil deposit is developed. The method is based on an improved understanding of the physics of the problem, substantiated by the results of extensive rigorous parametric studies using the boundary element method, and including analytical and numerical results available in the literature. Analytical expressions and dimensionless graphs are developed, applicable to both saturated and unsaturated soils, a variety of basemat shapes, and a wide range of embedment depths and types of contact between the vertical sidewalls and the surrounding soil. A numerical example illustrates the applicability of the method, while a companion paper (Fotopoulou et al. 1989) presents a simple method for determining the radiation damping of embedded foundations.
