| 摘 要： | 在盾构隧道衬砌受力分析中需要按最不利的荷载组合方式进行验算，这无疑加大了工程设计人员的工作量。正是基于这种状况，提出了考虑荷载工况组合的衬砌受力分析。首先建立了盾构隧道衬砌的结构分析模型，根据施工过程对荷载进行分类，依据规范对不同的工况进行荷载组合，得到衬砌内力包络图。并编制相应的计算程序进行了验证，对一典型盾构隧道截面进行了实例分析。

| Abstract: | During the analysis of cross-section forces of shield lining, the project must be checked by the method of the most unfavorable combination of the loads and it is doubtless to increase the workload of the designers. In light of the condition, an analytical method considering load combination is put forward. First, the structural analysis model of shield tunnel lining is established and different kinds of loads are classified on the basis of construction process and combined according to the design code for different working cases. Finally, the internal force envelope diagram is acquired. In the meantime, the computation program is accomplished and used in a project. |
