Analysis on theMechanism of Bolting-Grouting Technology for Changing and Strengthening the Rock Characteristic

摘要

Through the comprehensive analysis and research of the following four aspects: the basic principle of bolting-grouting technology for changing and strengthening the rock characteristic, numerical analysis, the mechanics mechanism and viscous-elastic analysis of surrounding rock deformation. This paper deals with three main aspects of the mechanism of bolting-grouting for changing and strengthening the rock characteristic. The author firstly brings up the four-layer valid combination arch theories, which can be viewed as some trials to the development of the bolting-grouting theories, and provides the reliable theory basis for improving the construction technique and bolting-grouting technology.
