摘要

In this paper,it takes the peach blossom valley tunnel as the study background and uses numerical computation method to contrastive analysis of double-arched tunnel design form and small-interval tunnel design form on loess.Through the comparative analysis of two kinds of construction method,it could take some conclusion: construction process of double-arched tunnel is complex,construct left hole and fight hole have a great effect on each other,it make the stress state of surrounding rock have complex changes during construction.The change trend of stress state of surrounding rock in small-interval tunnel is single,which is easy to predicate and control.
