本文提出了一种计算基岩上二维土结构地震反应的方法。该方法是基于Iwan提出的流变模型，考虑了土壤的非线性、滞后行为，并为结合土壤行为的实验室数据提供了相当大的灵活性。边界条件的近似处理，允许能量辐射到底层介质中。最后通过实例说明了该方法的有效性。
A method is presented for calculating the seismic response of two-dimensional configurations of soil resting on bedrock. The method, which is based on a rheological model suggested by Iwan, takes account of the nonlinear, hysteretic behavior of soil and offers considerable flexibility for incorporating laboratory data on soil behavior. An approximate treatment of the boundary conditions is employed which permits energy to the radiated into the underlying medium. Examples are shown to illustrate the method.
