Abstract

As a new tunnel structure form, double-arch tunnel is placed on the research stage at home and abroad. Since the stability of surrounding rock and its strain-stress have close relationship with the lining structure function appearance, the reliabilities of the support´s design parameters as well as the working procedure, the stress and displacement in the surrounding rock during different working stages of the double-arch tunnel and the stress and displacement law of the supporting structure achieved are analyzed in this paper, a reasonable excavation procedure, support procedure and the best support time are put forward on the basis of that. It is significant for the design and construction of the double-arch tunnel in China.
