Buoyancy Distribution Model and Cumulative Buoyancy of Shield Tunnel Considering Time-Varying Properties of Slurry
Published 2025-01-01“…Furthermore, a comparative model of the grouting test was established using the discrete element method. The particle meso-contact parameters in the numerical model were calibrated according to the test results, which were utilized to establish a numerical simulation model for synchronous grouting of the shield tail with continuous-discrete coupling, so as to observe the diffusion law of slurry in the shield excavation gap and the surrounding strata, and clarify the dynamic buoyancy distribution pattern of the shield tunnel while considering the impacts of slurry solidification and grouting pressure. …”
