Simulation on the Construction Process of Double-arch Tunnel by ADINA

摘要：

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 supports 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.
