摘要

管片设计一直是地铁设计中亟待解决的难题之一。管片计算模型的建立主要是考虑接头和土层抗力两种因素对结构的影响。对现有管片计算模型的接头简化进行了改进，推导了改进惯用法模型的内力和位移求解公式；并结合北京地铁10号线工程实例资料，对惯用法模型及改进模型进行了对比分析，与数值计算结果进行了综合验证分析。研究结果表明，推导的公式是可靠的，对地铁管片的设计和施工具有理论和实践意义。

Abstract

The design of segments is still one of biggest problems in the design of metro which are required to be solved. For building calculating model of segments

the effects of joint and ground reaction on the structure are considered mainly. We improve simplification of joint in the calculating model of segments

and deduce the formulae for solving inner forces and displacement problems in the improved model with routine method. Taking Beijing Metro Line No.10 for example

the routine method model is analyzed and compared with its improved model; and the results of numerical solution method are analyzed by comprehensiveness and verification. The study results show that the formulae derived are reliable

which are significant to the design and construction of tunnel segments in theory and practice.
