摘要

The calculation of lateral stiffness reduction factors of shield tunnel in the domestic is used by modified routine method for analyzing.At the same time, the lateral stiffness reduction factors of structural model has been investigated.Analyzed the existing efficiency of lateral stiffness values of shield tunnel in domestic and in abroad, the stiffness is determined in the range between 0.5 and 0.8.The reasonable about the range of the stiffness has been verified through the simulation about the lateral stiffness of structural model of shield tunnel segment joint.
