Abstract：The static parameters of rock and soil mass are absolutely necessary for engineering practice. Static mechanical test is a direct approach to obtain these parameters，but it is often difficult because of its heavy equipment，long duration，and high expense. The dynamic test，based on the theory of elastic wave propagation，is much easier than the static test due to the light equipment，flexible methodology，and smaller expense. Comprehensive utilization of the static and dynamic parameters of rock and soil mass will bring engineering considerably technical and economic benefits. In order to overcome the influence of the error in the measurement of travel time of waves，the fitting analysis of seismic phase in wave velocity test is conducted in-situ，and a series of rules and criteria to revise the travel time measured on rock and soil specimens are put forward. The characteristics of static test and dynamic test and their synthetic utilization problems are also discussed.
