| 摘 要： | 介绍了管片结构内力的理论,并采用相关有限元软件,通过北京某地铁盾构隧道的工程实例计算,给出了相应的轴力图和弯矩图,以此比较修正惯用法和梁-弹簧法在管片结构设计时的区别.而且,根据管片内力,分析两种最不利组合,验证了梁-弹簧法的合理性,指出梁-弹簧法更加适合于地铁盾构设计.最后,提出了地铁盾构隧道的设计建议以及管片裂缝控...

| Abstract: | The paper introduces the theory of internal force of segments,and uses the relevant finite element software to calculate an example of the subway in Beijing shield tunnel engineering.The schema is used to com-pare with M-K method and modified method in structural design to tell the difference between them.Thena,c-cording to the internal forcet,he most adverse combination of two kinds of the method is analyzed to verify ra-tionality of M-K method,and to prove that M-K method is suitable for subway structural... |
