Abstract

Abstract:

Taking the construction of a largespan urban traffic tunnel as example, for which single side drift method is adopted, the paper studies on the effects of different crosssection shapes and dimensions of side drifts on the ground surface subsidence, crown settlement, invert heaving and forces undertaken by the reinforcement structures by means of 2D elasticplastic finite element numerical simulations, which can provide basis for the design and construction of similar tunnels in the future.

Key words: , largespantunnel single side drift method , numerical simulation
