EXPLORATION AND APPLICATION OF SEISMIC ANALYSIS IN THE WAVE VELOCITY TEST OF ROCK MASS IN SITU

摘要

Wave velocity test in situ is an important approach to explore the engineering properties of the rock mass. In practice, many factors may affect the waveforms, so precise traveling time of seismic phases is seldom measured from the wave data. In order to overcome this obstacle, a series of rules and criteria for seismic phase analysis are put forward in this paper. The rational travel time of P and S wave can be obtained in the light of these criteria and rules. The method has been applied to the test of the rock mass in situ for a project, and a very good effect of the rock mass classification has been obtained.
