Risk Analysis of Shield Metro Tunnel Joint Leakage
Water leakage is one of the most serious diagnosis in metro shield tunnel.This study firstly analyzed joint open calculation of shield tunnel under transverse convergence and longitudinal deformation.Based on the stress-deformation and service performance development law of the contact surface of the waterproof sealing gasket,the mechanism of joint leakage was studied.Thus,the contact pressure of waterproof sealing gasket at joint can be obtained as a function of cross-sectional convergence deformation,longitudinal settlement curvature radius,and circumferential dislocation,which has certain guiding significance for the risk analysis of joint leakage.
