The research on the methodology of weighted average evaluation for surrounding rock stability of tunnel
摘要
Abstract
Surrounding rock stability evaluation of coal tunnel is the basis for judging the level of support difficulty and carrying on support design. Based on analysis and selection of the influence factors on surrounding rock stability and evaluation index, this article proposed an evaluation method of multi-factor single comprehensive index value. AHP Analytic Hierarchy Process is utilized to determine the weights of evaluation factor and weighted average method is to establish calculation models and calculation methods for single comprehensive index value. The results showed that the method of weighted average evaluation for surrounding rock stability of coal tunnel can reflect the stability characteristic of surrounding rock scientifically and provide a reliable basis for rock control and support design.关键词
