一次公路隧道轴线偏位的处理

Treatment of once highway tunnel axial deflection

分析了某高速公路隧道产生偏位的原因,经综合比较,采用桥梁和路基加宽的方案,并对工程施工过程中应注意的操作要点进行了系统分析,实践表明该方案较好地解决了隧道轴线偏位问题。

The paper analyzes the highway tunnel deflection causes. Through comprehensive comparison, applying bridge and subgrade widening scheme, it systematically analyzes engineering construction points. Practice proves that： the scheme better solves tunnel axial deflection problem.
