摘要

中国的地铁建设进程正在快速发展。盾构隧道以其灵活性强、成本效益好、对地面交通和地面结构影响小等优点在软土地基中得到广泛应用。用钢螺栓连接的节段预制混凝土衬砌(见图1)是盾构隧道中常用的一种施工方法。这些是隧道总成本中最重要的因素之一，占总成本的15-40%(1994年数据)。管片接缝开缝是盾构隧道施工中常见的问题，是两个混凝土管片衬砌之间的半刚性连接的力学行为

Mechanical behaviour of semi-rigid connections coupling two concrete segmental linings

INTRoduCTIoN The process of subway construction is undergoing rapid developments in China. Shield-driven tunnels are widely used in soft ground because of their flexibility, cost-effectiveness, and minimal impact on ground traffic and surface structures. Segmental precast concrete linings (see Figure 1) connected by steel bolts are commonly used in shield-driven tunnels. These are one of the single most important elements in the total cost of tunnelling, representing 15–40% of the total cost (Iftimie 1994). Segment joint opening is a common problem in shield tunnel operations, and is Mechanical behaviour of semi-rigid connections coupling two concrete segmental linings

期刊介绍： The Journal of the South African Institution of Civil Engineering publishes peer reviewed papers on all aspects of Civil Engineering relevant to Africa. It is an open access, ISI accredited journal, providing authoritative information not only on current developments, but also – through its back issues – giving access to data on established practices and the construction of existing infrastructure. It is published quarterly and is controlled by a Journal Editorial Panel. The forerunner of the South African Institution of Civil Engineering was established in 1903 as a learned society aiming to develop technology and to share knowledge for the development of the day. The minutes of the proceedings of the then Cape Society of Civil Engineers mainly contained technical papers presented at the Society''s meetings. Since then, and throughout its long history, during which time it has undergone several name changes, the organisation has continued to publish technical papers in its monthly publication (magazine), until 1993 when it created a separate journal for the publication of technical papers.
