Calculation and Analysis of Longitudinal Settlement Joint of Shield Tunnel Based on Dual Elastic Foundation Beam
Based on the model of dual elastic foundation beam, considered the effect of uneven settlement of soft layer, and treated the interaction between structure and soil as a plane problem, a plane numerical model is established. Then, the arrangement of settlement joint and the force and deformation of tunnel longitudinal structure are calculated and analyzed. By calculating that, the model can make full consideration of all factors which affect the uneven settlement of the tunnel, especially for the calculations of the settlement of tunnel in complex conditions. The obtained conclusions give reasonable data about the arrangement of settlement joint of the Yangtze River tunnel, and throw lights on the design and construction of tunnel segments in the future.
