摘要
根据现行的《公路隧道设计规范》和《公路工程地质勘察规范》的有关要求,对岩体质量系数进行分级,分级中选择了7个地质因素和6类围岩指标,并与稳定性相对应,构成了隧道围岩分类质量标准表。在此基础上,分析了围岩分类诸因素及各自特征,采用模糊综合评判的方法,建立了隧道围岩的数学模型,使围岩分类变得简单易行。
According to the requirements under the current Highway Tunnel Design Specifications and the Highway Engineering Geological Survey Specifications, rock quality eoefficient should be classified, in which seven geological factors and six types of surrounding rock indicators are selected corresponding to stability and become the quality standard for the tunnel surrounding rock. Based on the standard, in-depth analysis is made of each of the factors and its characters considered in the classification, and a mathernatie model is established by use of fuzzy comprehensive assessment method, making the classification simpler and easier.
