The aim of this research was to explain the effects of relative density, mean effective stress, grading characteristics, consolidation stress ratio and initial fabric anisotropy produced during specimen preparation on shear wave velocity (V_s). It is shown that the V_s of the consolidated specimens under anisotropic compression stress is greater than that of the consolidated specimens under isotropic or anisotropic extension stress states at a given relative density and effective confining stress. It is also shown that the depositional technique that was used to create reconstituted specimens has important effect on the V_s. A parallel comparison of measured values from the resonant column and bender element tests is also presented. These results of the tests have been employed to develop a generalized relationship for predicting V_s of granular soils. The V_s model is validated using data collected from literatures. Based on the results, it can be conducted that the proposed model has a good performance and is capable of evaluating the V_s of granular soil.

本研究的目的是解释试样制备过程中产生的相对密度、平均有效应力、级配特性、固结应力比和初始织物各向异性对剪切波速度 ( V _s ) 的影响。结果表明，在给定的相对密度和有效围压条件下，各向异性压缩应力下固结试件的V _s大于各向同性或各向异性拉伸应力状态下固结试件的V _s。还表明，用于创建重组标本的沉积技术对V _s具有重要影响. 还介绍了共振柱和弯曲元件测试的测量值的平行比较。这些测试结果已被用于开发预测粒状土壤V _s的广义关系。该V_小号模型使用来自文献收集的数据进行验证。结果表明，该模型具有良好的性能，能够评估粒状土壤的V _s值。
