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。 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.
