Influence of Hardening Time and Concrete Grade on Rock Bolt Testing with Reflected Wave

Abstract

Abstract:

The physical model of rock bolt testing with reflected wave was analyzed and solution to the wave equation with damping coefficient was given. Besides, two analog experiments for different concrete grade and different hardening time were conducted. The experiments indicate that the hardening time has a greater influence while concrete grade has a minor influence on rock bolt testing.

Key words: reflected wave, rock bolt quality, testing, hardening time, concrete grade

CLC Number:
