| Abstract: | About the problem of the interface determination of strongly weathered granite in the south of Fujian province, the quantitative evaluation can be performed by the blow counts N of standard penetration test(SPT), but the correction of N has different definitions from various technical regulations. In the paper, the shear wave velocity results act as a reference standard, combining with experimental discrimination, by analyzing the measured data of engineering project, finally, it is considered that the correction of blow counts N should be conducted. |
