探讨适用于近海及潮间带场区的剪切波速原位测试方法，针对黄海小洋口潮间带，进行剪切波速的原位测试，分析剪切波速的变化规律及其与土体参数的统计关系，并建立复合关系进行剪切波速预测分析，同时基于剪切波速测试成果进行应用分析。研究结果如下：通过经适性对比，近海及潮间带剪切波速测试采用单孔悬挂式方法较为适宜；剪切波速与测点深度呈相关性较好幂函数关系，按土层的统计关系分析，幂函数及其误差包络线基本反映了规律性；与土体物理力学参数的统计关系呈相关性较好幂函数或线性关系；基于测试资料，建立剪切波速Vs、孔隙比e、密度ρ及有效自重应力σ′的复合关系，通过计算对比分析，按此方法可以取得良好的剪切波速预测结果，亦可进行相关指标的预测分析；通过原位测试资料，进行场地土类划分对比、动参数规律性分析及地震液化判定分析，可为工程勘测、设计人员提供参考。

Test methods which are suitable for testing shear wave velocity in the offshore site and intertidal zone are studied and compared. The shear wave velocity in-situ test for the Xiaoyangkou intertidal zone of Yellow Sea is conducted. The statistical relationships between change law of shear wave velocity and soil parameters are analyzed and the shear wave velocity is predicted by the built relationships. In addition,some applications of test data are analyzed. The research results show that:(1) The suspension test method for shear wave velocity is appropriate in the study site by the comparison of economic applicability. (2) There exist power function relationships between the shear wave velocity and the depth of test data and they have a good relativity. In the meantime,according to statistical relationship analysis of soil layers,the correlations and envelope curves basically reflect their regularity. (3) The relationships between shear wave velocity and soil parameters are power or linear functions,and they correlated well. (4) Based on the test data,compound relationships are established among shear wave velocity Vs ,void ratio e,densityρ and effective gravity stressσ′. Based on the methods, good function results can be achieved through the contrast analysis of the calculation results;and other prediction analysis for relative parameters can also be performed. (5) Furthermore,based on the in-situ test data,soil type classification,dynamic parameters calculation and earthquake liquefaction judgments are carried out. The methods and results can provide references for survey and design engineers.
