Abstract
Based on the histogram and shear wave velocity data of 449 boreholes in the Jiaozhou Bay area of Qingdao, the empirical relationship between soil depth and shear wave velocity is calculated. The empirical relationship and sedimentary environment characteristics are analyzed. In connection with the soil layer, which has a long transport distance and a relatively small particle size, the shear wave velocity is relatively low. The empirical relationship between depth and shear wave velocity in the depth of 20m depth of the soil layer with obvious sedimentary features in the Jiaozhou Bay area of Qingdao is given. For the soil layer without obvious sedimentary features, the sedimentary features of the remaining strata of the borehole are used for classification, which improves the fitting degree of the empirical relationship and reduces the error, thus giving a method to estimat shear wave velocity of borehole using bore histogram with obvious sedimentary characteristics.
