摘要
采用梁 -非线性弹簧模型 ,对盾构隧道通用装配式管片衬砌在基本拼装方案下各典型计算点进行最大截面内力及变形计算 ,确定管片设计控制荷载点 ;并在通用管片衬砌环布置时可能出现通缝及错缝拼装情况下进行多种方案组合计算 ,进而确定控制管片设计的拼装组合 。
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.
