    • Abstract
  • Using orthogonal experimental method, the finite element software ANSYS numerical simulation, this paper attempts to optimize roadway bolt supporting scheme. The length of rock bolt, anchor bolt diameter and spacing were used as the research factors. Through the analysis of orthogonal test, the paper determined the maximal influence factor on the stability of tunnel, and got the best support scheme. The results showed that this method was more efficient than the experience one, which could quantitatively determine the quality of bolting.
