摘要
在隧道开挖施工过程中,经常会遇到围岩失稳,变形的问题。本文结合了宁德至武夷山高速公路S4合同段下洲隧道工程,利用灰色聚类法对隧道围岩分级进行了分析计算,对比传统分级法与灰色聚类法两种分级结果,并对隧道开挖施工后围岩稳定、支护提出了意见。
In the course of excavation of tunnel,the problems of rock stability,deformation and damage are often encountered. In this paper the tunnel projects of the Ningde to Wuyishan S4 highway contracts and Bidanya Tunnel Engineering of the Chengdu-Shanghai highway are combined,and the knowledge of Rock Mechanics and Gray Theory are used in the surrounding rock classification and calculation of stability analysis.At the same time,this paper puts forward the suggestion to the rock stability after the excavation of the tunnel, and discusses whether to need supporting or not.
