Abstract

In order to determine the structural changes of the tunnel before and after the construction of the adjacent project, and to control the diseases within the specified range, based on the deep foundation pit project around the Jiubao Metro in Hangzhou, the maximum displacement results of the typical cross-section tunnel before and after deep foundation pit excavation and reinforcement calculated in PLAXIS were extracted, and the joint bolts, steel mesh, etc. were considered in the model established by DIANA. The displacement superposition of the refined single ring lining model was carried out, Analyze the damage of tunnel lining structure through two-stage calculations and verify the effectiveness of reinforcement measures. The research results indicate that the structural damage of the tunnel is more severe after deep excavation, and the reinforcement measures have a good control effect on the deformation of the tunnel. The two-stage refined model can quantify the lateral structural damage of the pipe segment and obtain the crack width to study the specific development trend of the pipe.
