【摘要】 讨论了高阶模态面波位移幅度占优势并由于高阶模态面波的影响、难以提取完整的基阶模态面波的频散曲线的情况下,利用"最大模"频散曲线进行反演解释的必要性.对软夹层型和地表为高速层两种高阶模态面波位移幅度较强的地层结构的理论和实测"最大模"频散曲线进行反演研究,获得了比仅利用基阶模态面波解释更好的效果.同时还讨论了初始模型建立和反演方法等问题.更多还原

【Abstract】 It is discussed that the necessity of inversion explanation with max-mode dispersion curve when the high-mode Rayleigh wave energy is dominant and difficult to get the fundamental-mode dispersion curves.It is shown that the inversion effects of max-mode are better than that of fundamental mode by theoretical inversion modeling and field datum inversion of max-mode dispersion curves of two kinds of high modes dominates layer structure such as low velosity model and pavement systems model.Initial model creation and inversion method are discussed.更多还原
