利用有限单元法及解析法建立和求解了土中Love波特征方程以及位移计算公式．计算结果表明，这一计算方法比纯解析法优越，可以用来分析均质和非均质上中Love波弥散性．本文利用这一方法详细讨论了Love波在上软下硬地基及软夹层地基中的传播特性和弥散特性．上软下硬地基Love波具有弥散性，土层的剪切波及厚度对Love波弥散曲线影响较大，而质量密度的相对变化对Love彼弥散曲线影响较小．软夹层地基中低频时Love波以第一模态波为主，现场所测为第一模态波波速；高频时存在多个高模态波，土中传播的波为这几个高模态波的叠加波，现场所测波速随两传感器的位置不同而有波动．
The finite element method and analytic method were used to establish and solve the characteristic equation of Love wave in soil and the displacement calculation formula. The calculation results show that this method is superior to the pure analytic method and can be used to analyze the diffuseness of Love wave in homogeneous and inhomogeneous medium. In this paper, we discuss in detail the propagation and dispersion characteristics of Love wave in the upper and lower soft ground and soft interlayer foundation. Loose soft ground Love wave has diffuse, soil shear wave thickness and thickness of the Love wave dispersion curve greater impact, and the relative change in mass density on Love Bi dispersion curve less affected. Love wave in soft mezzanine ground is dominated by the first mode wave at the low frequency, and the first mode wave velocity is measured at the site. There are several high mode waves at high frequency. The waves propagating in the soil are the high modulus State waves superimposed wave, the measured wave velocity with the two sensors have different positions and fluctuations.
