Abstract
Two different up-hole methods are proposed for measuring the wave propagations generated by the standard penetration test to investigate the shear wave velocity. The results are compared with the conventional PS logging test (down-hole method) to evaluate the reliability of the shear wave velocity measured by the up-hole methods. As a result, comparison of both shear wave velocity shows good agreement. Therefore, the shear wave velocity generated by the standard penetration test is found to be reasonable in engineering practice.
