中文摘要：

为了更可靠地获取场地土动剪模量．利用JB型波速仪．采用单孔法．现场对场地土分别沿1．80m、2．80m、3．65m和6．65m深度进行了波速测试．得到了场地各层土的剪切波速。此外．取出了场地各层土的原状土样．进行了室内循环单剪试验．获得了各层土的动剪模量．并与剪切波速的计算结果进行了比较分析。结果表明．由现场剪切波速试验和室内循环单剪试验得到的最大动剪模量比较接近．说明两种试验的结果都比较可信．两者可以相互验证，建议实际应用中将两者综合考虑。

英文摘要：

To get reliable dynamic shear modulus of site soil, wave velocity of site soil is tested in situ along the depth of 1.80 m,2.80 m,3.65 m and 6.65 m by using single hole method with the JB type of wave velocity apparatus, and the shear wave velocity of each layer soil is obtained. Furthermore, undisturbed samples of each layer soil are taken out, and the maximum dynamic shear modulus is obtained by laboratory cyclic simple shear tests. The results between cyclic simple shear test and shear wave velocity field test are analyzed Comparatively. It is showed that the maximum dynamic shear modulus obtained from cyclic simple shear test is close to that of shear wave velocity field test, so the results of two types of tests are creditable, and can approve each other. It is suggested that, in practice, the adopted modulus must be determined by comprehensively considering the results obtained from experiment and field test.
