地面木板敲击方法和悬挂式井中测试方法是工程中常用的两种剪切波速测量方法。在长期的工作中发现，对于类似的场地，不同的方法所得到的测试结果有时存在一定的差异。为此，选择了山西地区5个场地条件不同的比较典型的地震钻孔，分别采用两种方法对同一钻孔进行测试，并对结果进行了比较和分析。结果表明，在钻孔地层为土和砂且钻孔质量较好的情况下，两种方法所测数据相差不大，一般相差在10％以内。钻孔质量较差，局部有轻微塌孔、缩径的情况时，采用悬挂式测井方法误差较大。对于含有卵石地层的钻孔以及需要测量基岩面以下的地层剪切波速的钻孔，则应采用悬挂式井中测试方法。

Both methods to generate stimulus by plank tapping on the ground and by hanging device in well are common in shear wave velocity measurement .It is found that the results have been having some differences with different methods for long time .There-fore ,5 boreholes in different site conditions in Shanxi Province are tested by using both methods respectively and results are com-pared and analyzed .The results show that the testing results are marginally different if the stratum is soil or sand on the conditions of good quality of borehole ,different within 10% .Whereas there are slight collapse or shrinkage inside borehole ,it will have larger errors with the method of stimulus by hanging device in well .Furthermore ,in cases that stratum contains gravel layers or to meas-ure shear wave velocity under the bedrock surface ,the method of stimulus by hanging device in well will be a better one .
