浅埋偏压且下穿道路黄土隧道施工技术探讨

Shallow bias and tunnel under the wear of road construction techniques of loess

通过对太中银铁路穆村1号隧道出口浅埋偏压段且下穿地方道路状况的分析,采用回填反压、路面处理、洞内各施工步序距离等方案方法,确定了合理的施工技术方案,成功解决了隧道在浅埋、偏压及下穿道路所面临的综合不利问题。

On the basis of the analysis about the exit of the No. 1 tunnel of Tai-Zhong-Yin railway Mu village, which on the section of shallow bias and underpass of local road, adopting the methods such as anti-backfiU pressure, pavement treatment, the construction sequence distance inside the cave. We make sure the reasonable construction technique projects and resolve the comprehensive and disadvantageous problems suecessfully, which the tunnel on the section of shallow bias and underpass of local road faces on.
