摘要
双洞8车道特大断面隧道是最近几年以来公路交通发展的趋向。现根据国内外在该领域所取得的研究成果,着重对双洞8车道的净距优化、围岩压力、支护设计和施工方法等进行介绍。通过总结前人研究成果,指出目前双洞8车道隧道研究存在的问题,提出了未来研究的发展方向。
The eight-lane large-section twin tunnel is the trend of highway traffic development in the recent years. Based on the study results of this field at home and abroad, the paper focuses analysis on the spacing optimization, surrounding rock pressure, support design and construction methods of eight-lane twin tunnel.Through the summary of previous study results, the paper points out the problems existing in the study of eight-lane twin tunnel now, and puts forward the development direction of future study.
