错缝拼装盾构衬砌结构力学性能试验分析
|
摘要
错缝拼装盾构隧道衬砌结构由于存在环间传力行为,具有与通缝拼装衬砌结构不同的力学特性。文章通过三环压弯试验获得错缝拼装管片的极限承载力和力学行为规律,分析了衬砌结构纵缝、环缝及管片本体的相互协同作用,并通过一系列试验设计工况得到了纵向力和荷载水平对结构性能的影响规律。同时对比分析了三环与单环压弯试验结构的受力特性和破坏模式的差异,获得错缝拼装盾构衬砌的力学性能和环间传力效应。
Because of the force transmission between adjacent rings, the mechanical behaviors and failure patterns of staggered segment lining are diametrically different from that of segment with straight joint. In this paper, threering bending experiments were carried out to obtain the ultimate bearing capacity and mechanical behavior of staggered segment lining, the synergy of longitudinal joint, circumferential joint and segment itself was analyzed, the influence of longitudinal force and loading level on structural properties was obtained through a set of designed conditions. By comparing the mechanical behaviors and failure patterns of three-ring bending experiments and singlering bending experiments, the mechanical behaviors of staggered tunnel segment lining and force transmission between adjacent rings were gained.
