摘　　要：国内外学者已对桩-土相互作用的弹性模型做了大量的先期研究。将该模型应用于桩基动力响应和沉降计算。利用该模型计算桩基沉降具有如下的优点:容易与工程中广泛采用的有限元软件如ABAQUS结合;只要合理选取模型参数,就可模拟桩端下所有压缩土层的沉降量,而现行规范计算桩基最终沉降量时,只考虑了计算深度内土层的压缩量。动力和静力工程算例计算结果表明,该方法具有较高的精度。Early and advanced research work of elastic model for pile-soil interaction has been studied widely at home and abroad. A method of using the elastic model to calculate the settlement and dynamic response of pile foundation was presented in this paper. Using the model to calculate settlement of pile foundation has the following advantages： the model is easily to combine with finite element software widely used in engineering such as ABAQUS. If we can reasonably select the model parameters, settlement of all compressible soil layers under the pile, can be simulated, while the current code method only considers the final settlement of pile foundation. Dynamic and static engineering examples show that the method has higher precision.
