Abstract

Abstract: The nominal adhesion strength between the rock anchor grout and heavily weathered slate rock mass Lower Series of Silurian Period was back-analyzed from the in-situ critical testing on four rock anchors. The influence of the grout length on the nominal adhesin strength was evaluated and the critical grout length in the similar geological conditions was also proposed. The influence of the borehole installation, and grouting procedures on the nominal adhesion strength was also investigated.

Key words: slope stabilization, ground anchors, critical tests, nominal adhesion strength between grouts and rock mass
