摘要
基于软土固结中剪切波速度增值与固结度的关系理论,介绍了面波勘探技术与原位监测、室内土工实验成果紧密结合,检测分析软土地基处理固结效果的方法,并分析了测试固结度的系统误差,提出浅层地基固结度的测试准确性高于深层地基.结合浙江省玉环县漩门二期供水蓄淡围垦工程,说明了该方法的准确性和实际工程意义.
The method of the surface wave exploration technique in combination with in-site test and indoor soil test results for verifying the consolidation effect of soft clay foundation is introduced in the paper according to the relation theory of shear wave velocity increment and consolidation degree.The systematic error of testing degree of consolidation is analyzed.The viewpoint that the accuracy of testing degree of consolidation in shallow foundation is higher than in deep foundation,is given.The accuracy of the method and actual meaning are also illustrated.
