Abstract
Based on the Chenjiaqiao tunnel project, the construction process of tunnel under different surrounding rock conditions and with various construction methods is analyzed with MIDAS program. The mechanical behavior under complex process of construction and the optimization of the construction process of multi-arch tunnel are studied by the analysis of the monitoring measured data and the numerical analysis results. The main contents of the research contain: The 3D elastoplastic model of multi-arch tunnel is set up, which contains Grade III, IV and V surrounding rock. The stress of the surrounding rock and the supporting structure at typical excavation stage under above three excavation methods are simulated and analyzed. The monitoring data is analyzed and compared with the simulated data. The reasonable distance between the working faces of the right and left tunnel is obtained.
