RESEARCH ON DESIGN AND COMPUTATION METHOD OF SHIELD TUNNEL LININGS IN COMPLEX STRATIGRAPHIC CONDITIONS
-
摘要: 隧道衬砌结构设计模型随着国际技术合作和交流的增加而趋于一致，但各国对衬砌结构计算理论的研究从来没有停止过，提出了越来越多的计算模型。针对盾构隧道施工过程中的施工步骤、管片与土层接触面并结合盾构施工的特点，利用应力释放系数的概念，建立了模拟盾构隧道衬砌施工全过程的有限元分析方法，进行了有限元模拟分析。对隧道衬砌的优化设计提供参考。Abstract: As the technical cooperation and communication are frequent in the world, models for tunnel lining design are becoming unanimous, but the researches for appropriate computational models have never been stopped and more and more of them have been brought out. Accoring to tunnel construction steps, contact surface between segments and soil and stress releasing, 2D-FEM is put forward to simulate shield tunnel construction.The conclusion and methods can provide valuable preference for tunnel linings optimization designs.
