摘要
为研究地铁隧道衬砌在侧向荷载作用下的极限承载力和变形能力,上海申通地铁集团有限公司和同济大学近期完成了基于地铁隧道变形治理的衬砌整环极限承载能力试验研究。介绍了地铁衬砌结构整环试验的研究内容,包括加载装置、荷载设计、测试内容以及部分试验结果等。
In order to study the ultimate deformability and bearing capacity of the Metro tunnel lining ring subjected to lateral force, Shanghai Shentong Metro Group Co. Ltd. and Tongji University have recently carried out a test on the ultimate bearing capacity study of a 1：1 scale full-ring lining structure based on the deformation treating of the metro shield tunnel. This paper introduces the testing processes, including the design of the loading apparatuses, the load, the test contents. Some experimental results are presented.
