摘要

Studies related to the application of stress wave theory to Standard Penetration Test(SPT) in Japan are introduced together with a report on the discussions we have had on the dynamics and mechanism of the SPT as well as aspects of the issues to be studied. Uto et al. were the first to apply the stress wave theory to the SPT in 1970's. Matsumoto et al. have applied the method of two-point strain measurements to the SPT, and presented the calculated stresses, penetration and transmitted energy as functions of time in diagrams which corresponded reasonably with measured data. Fujita et al. have proposed a fundamental equation for the equilibrium between the driving and resisting energies considering the energy transfer ratio, an adjustment method for N-values, and Fujita's diagram summarizing the SPT results, etc..
