摘要

摘要: 以某盾构衬砌整环原型试验作为研究对象,利用提出的接头和管片破坏指数对盾构衬砌环的破坏机理进行了研究,研究表明：①接头破坏指数和管片破坏指数以及开裂弯矩等指标可以对盾构衬砌的实际受力状态进行追踪,可以阐述、解释盾构衬砌环的破坏机理；②对于本文所依据的盾构原型试验而言,盾构衬砌环破坏历程是由接头开始开裂、管片开始开裂、首个管片塑性铰形成、接头开始屈服（接头开始丧失承载力）、多个管片塑性铰形成、整环承载力丧失等阶段构成；③多个塑性铰的形成是导致盾构环承载力丧失的直接原因,塑性铰开始位置、发展顺序取决于关键截面及其排序情况。

Abstract: To study the failure mechanism of segmented tunnel lining in the ultimate limit state, 3-rings full-scale tests on a segmented tunnel are performed by applying ovalisation load, and the failure history is analyzed by means of the parameters of failure index of segments and segment joints. The results show that the load bearing state and failure possibility of the component of the tunnel can be traced effectively, and the failure history can be described and explained according to the two parameters. The prediction of the crack and crush of the test tunnel rings can be verified by the observed and measured data obtained from the prototype tests. The failure history of the segment tunnel lining is composed of the crack initiation of segment joints, crack initiation of segments, formation of plastic hinge in segments, yielding of segment joints, development of multiple plastic hinges in segments and loss of the load bearing capacity of the whole rings. The initiation location and development sequence of plastic hinge in segments are influenced and controlled by the critical cross-sections in rings of the segmented tunnel lining.
