基于Hoek-Brown模型的铁路隧道围岩分级研究
Study on Classification of Railway Tunnel Surrounding Rock Based on Hoek-Brown Model
摘要
Abstract
Railway is a kind of typical zonal traffic engineering and the railway in mountain area usually encounters on its way many complex geological conditions and heavy geologic investigations are required. In order to analyze quickly the mechanical macroparameter and fulfill surrounding rock classification based on conventional geology survey, the macroparameters of surrounding rock are estimated according to Hoek-Brown failure criterion. The analysis and classification model is presented based on general investigation and indoor test of rock mass. In addition, the estimation software for solving rock mass mechanical parameters is completed with C # to analyze the mechanical macroparameters of surrounding rock. The value of GSI is most sensitive to affect the mechanical macroparameters of surrounding rock shown by sensibility analysis, and the mechanical macroparameters and classification of surrounding rack are conducted with the program in this paper, which may serve to guide the design of Daozhazi Railway Tunnel.关键词
