    摘要:

    论述了盾构隧道管片衬砌内力计算的梁-弹簧法和弹性匀质圆环法。结合一工程实例,采用此两种方法对管片衬砌内力进行了计算,并对计算的结果进行了对比分析。结果表明,采用梁-弹簧法进行设计是安全的、经济的,值得推广应用。

    Abstract:

    The elastic-inhomogeneous-ring method and beam-spring methods of internal forces calculations for the shield tunnel lining are discussed in detail.As a traditional method of shield tunnel lining designing,the elastic-inhomogeneous-ring is safe but conservative.Combining with a practical engineering example,its internal forces were calculated respectively by the two methods.The results of these two methods were compared and analyzed,and drew the conclusion that the beam-spring method for the designing of the shield tunnel lining is safe and economical.
