摘要
本文以模型桩为例，进行了小应变反向波数值分析方法研究。采用一维波动议程和有限元离散方法，并把它与特生解法有效地衔接起来。文中研究了如何减小由有限元离散引起的弥散现象，以及采取优化的方法选取参数的可能性。采用本文方法，研究了完整模型桩中应力波的传播规律，计算了顶端的响应，并与实测曲线进行了比较，两者吻合较好。
In this paper, taking a model pile as an example, the numerical analysis of the back waveof little strain has been carried out by one-dimensional wave equation and the discrete method of finiteelement and it is effectively combined with characteristic line method, It also studies how to reduce thescattered phenomenon caused by discrete method and the possibility of selecting parameters by optimummethod. The laws of stress wave propagation in a integrated model pile have been researched and response on it's top is conputed by the paper's method. The computed results coincide with tested those bycomparing with each other.
