摘要
本义利用ＷＫＢＪ近似（即几何近似）理论研究介质参数随深度作连续变化的竖向非均匀弹性半空间上覆盖一层厚度为Ｈ的均匀各向同性的弹性介质时Ｌｏｖｅ面波的频散问题，给出其频散方程。文中以剪切弹性模量和质量密度随深度呈抛物线变化的非均匀介质为例，给出其最低阶振型的频散曲线。
he WKBJ approximation method is used to solve the dispersion problem of Love waves in a depth - dependent vertical inhomngeneous elastic half-space covered with an isotrnpic homogeneous elastic layer whose thickness is H and the dispersinn equatinn is presented. As an example an inhomogeneous medium is studied where the shear modulus and mass density are parabolic and the dispersion curve of the lowest order vibration type is given.
