摘要

利用叠加原理发展了管模型，克服了管模型不能计算自由表面处的振动反应和只适用于深埋隧道的缺陷。土体中任意一点位移表示为波数-频率域的函数，经傅立叶逆变换获得空间域的反应值。应用MATLAB编制了计算程序，对振动波在隧道和土体中的传播规律进行了分析。

Abstract

Using superposition principle progress the pipe model and the defect that the model is only applicable deep buried runnel is overcome. The coupled problem is solved in the frequency domain by Fourier decomposition into ring modes circumferentially and a Fourier transform into the wavenumber domain longitudinally. A software system is developed based on MATLAB. The vibration transmission law of tunnel and soil are analyzed.
