Abstract

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.

Key words: shallow tunnel, Analytic Hierarchy Process (AHP), ring cut method, double side drift method, CRD method, CD method, numerical analysis
