| 摘 要： | 以我国城市地铁区间盾构隧道为对象,采用几何比 1/12、同时考虑盾构隧道管片接头效应和管片与土体相互作用效应,用三维土-盾构隧道相似模型试验对盾构隧道管片结构在不同拼装方式下的力学行为进行了研究,并将研究结果与梁-弹簧模型的理论分析结果进行了比较,得出的结论可为盾构隧道的设计提供参考。

| Abstract: | Based on the sectional shield tunnels of metro in China, mechanical behavior of segment structure of shield tunnel under the different erection methods has been studied with geometric proportion of 1:12 through the simulated model tests of 3D ‘ground-shield tunnel’ in which joint effects of segments and mutual action effects between segments and ground are considered. And the conclusion that has been drawn through comparing the obtained results with the theoretical results based on ‘beam-spring’ model can be presented as the references for the designs for shield tunnels. |
