本文以实际工程为背景，通过采纳合理的施工技术措施，顺利地解决了隧道洞口不良地质的施工难点，对大断面软弱围岩偏压隧道洞口施工具有一定的参考价值
Abstract： During the tunnel construction process， due to the influence of environmental factors such as topography and geomorphology ， many tunnel openings have unfavorable geological conditions such as shallow burial ， weak surrounding rock ， bias pressure and poor stability ， resulting in increased difficulty in construction
In order to ensure the quality ， progress and other goals ， it is necessary to adopt corresponding construction technology according to the site conditions of the project
This article takes the actual project as the background ， and adopts reaso
