Analysis and computation on universal assembling segment lining for shield tunnel

With beam nonlinear spring model,for each typical calculation point of the shield tunnel universal segment lining on the basic assembling plan carry out calculation of the maximum inner forces and deformation section,determine segment design control load point;on the condition of alternate and universal joint assembly when arranging universal segment lining carry out various scheme combination calculation,and then definite assembling combination of controlling segment design,and discover inner force and deformation tendency in section on different assembly plan.
