摘要
本文在有限层和有限元两种方法的基础上，提出了一种求解桩土相互作用的动力非线性反应的力学分析模型———动力层元分析模型。推导出相应的理论公式，将一个半空间的问题转化为准二维平面问题求解。经实例验证分析，此分析方法概念清晰，简捷、快速。
A new mechanical model the dynamic finite layer element model is proposed to analyze the dynamic nonlinear respose for pile-soil interaction based on the finite layer and finite element methods The corresponding theoretical formula is derived The spatial problem of semi infinite body is transformed to a pseudo two dimensional problem and solved It is shown by the results of some example that this method is convenient and reliable, and can be applied widely in the engineering practice
