摘要
通过对南梁隧道喇叭口段工程的地质条件、断面尺寸、工程耐久性等进行分析,提出了适合南梁隧道喇叭口段的单双线过渡结构形式。现场监控量测结果证明所选大跨结构过渡形式是合理、安全的。
Base on the analysis of geological condition,cross section size and engineering duration of Nanliang tunnel bell type section,the proper structure type from single track to double-track at the selction of tunnel portal is proposed.Site measurement results show that the large-span structure is reasonable and safe.
