双连拱黄土隧道中导洞施工技术探讨

The Discussion on the Construction Technology of Middle Pilot Tunnel for Double-arch Loess Tunnel

介绍了黄土双连拱隧道中导洞的施工工序,重点论述了中导洞中隔墙基底处理,以及中导洞基底处理前后监控量测的结果分析,说明基底处理方案的合理性,同时也说明中导洞中隔墙施工的重要性,为以后黄土隧道的施工提供参考。

This paper introduced the construction process of double-arch loess tunnel,and mainly discussed the base treatment of middle wall in the middle pilot tunnel, and the results analysis of monitoring measurement before and after base treatment, it illustrated the rationality of the base treatment scheme, at the same time,it also explained the importance of the middle wall in the middle pilot construction,provided the reference for the future construction of the loess tunnel.
