摘要

以浅埋公路隧道为研究对象，利用层次权重决策分析法对正台阶环形开挖法、双侧壁导坑法、交叉中隔墙法和中隔墙法等隧道施工工法进行对比分析，得出交叉中隔墙法能很好地控制地表沉降。结合FLAC3D软件，模拟交叉中隔墙法、正台阶环形开挖法施工后地表沉降，通过对比工程实际分析验证层次权重决策分析法。结果表明，层次权重决策分析法是选择开挖方法行之有效的方法，能为浅埋隧道施工方法的选择提供参考。

Abstract

Comparison and contrast are made among the ringcut method, double side drift method, cross diaphragm (CRD) method and the center diaphragm (CD) method by means of the AHP, on basis of the case study of a shallow highway tunnel. The conclusion is that the ground surface settlement can be well controlled by adopting the CRD method. The result of the ground surface settlement of the CRD method and the ringcut method is simulated with the help of FLAC3D. The AHP is verified by comparing it with the actual work condition. The study shows that the AHP is an effective way to select proper excavation method for tunnels and that it can provide reference for the selection of construction method for shallow tunnels.
