Design of Underground Engineering Analogy Based on Fuzzy Comprehensive Evaluation Model

Abstract:

In the design of underground engineering analogy, the division of rock mass level and the selection of support parameters are affected by many uncertain factors which share characteristics of random and obscurity. This paper lays the foundation of the classification of joint rock masses CSIR and supporting parameters recommended values, selecting several key factors affecting the stability of surrounding rock masses, and employing the methods of fuzzy comprehensive evaluation to divide the underground cavern, and having put forward the reasonable supporting parameters. The results show that the level of surrounding rock is the Ⅲ, meanwhile, it takes into account the proximity effects and designs the supporting parameters to the supports, as a result, this method has achieved comparatively reasonable and economic effects in the practical application.
