摘要

多道瞬态面波法基于在不均匀介质中,面波具有频散性.通过对频散曲线进行分析,可划分不同深度相应的面波,而面波与剪切波有密切关系.剪切波在建筑抗震设计中,可用于建筑场地类别划分,同时也是场地地震效应评价不可缺少的参数.通过工程实践,用统计方法建立剪切波与土体的标准贯入试验击数、地基承载力、黏聚力及内摩擦角等参数的关系,可间接提供强夯地基处理施工中,因客观原因,缺少土层参数的不足.为此,通过工程实例,说明多道瞬态面波法在强夯地基工程的应用效果.
Multi-channel transient Rayleigh-wave method is applied in non-uniform dielectric,such wave is dispersed.Through the analysis of frequency dispersion curve,it can be divided into different Rayleigh-wave according to relevant depth.Rayleigh-wave has close relationship with shear wave.Shear wave can be used to divide construction site in the aseismatic design.It is also a necessary parameter in the evaluation of earthquake effect.Through the statistical method which builds the parameter relationship between the shear wave and standard blow number,bearing capacity of foundation soil,cohesion,and internal friction angle.This can remedy the shortage caused by objective condition in the construction of dynamic consolidation foundation.The essay researches into the application effect of multi-channel transient Rayleigh-wave method on construction of dynamic consolidation foundation with examples.
