The Application of Getting R_c Value from Point Load Test and Rebound Test by Tunnel Surrounding Rock Classification System

Abstract:

The point load test and rebound tests were part of a simple rock testing methods, which together with a user-friendly, work environment characterized by less demanding test, so test the application of rock in the tunnel are very broad. Obtained by these two tests of rock uniaxial compressive strength Rc saturation level for the characterization of rock hard quantitative indicators, in the rock classification has a high status. With the computer technology in tunnel works in the field of application that can batch test data to establish the tunnel surrounding rock classification system. Article is based on two kinds of test in the same tunnel project in contrast to the use, through the rock classification system to analyze and evaluate both.
