厦门东通道海底隧道位移判定基准研究

由于量测技术、计算机技术的发展和渗透，隧道结构体系的反馈设计方法有了很大的发展。所谓信息反馈设计，实质上是通过施工过程中的大量信息（情报）来指导设计和施工，以期获得最优隧道结构物的一种方法。在信息反馈中，位移量测基准的设定是一个关键问题，为此，结合厦门东通道海底隧道实际情况，对位移判定基准进行了研究，以便现场使用。

Study on Displacement Judgement Criteria of Sub-sea Tunnel on Xia-men East Passage

Due to the development and intervention of the measurement technology and computer technology, the design method for the tunnel structural system based on information feedback technology has achieved great progress. The so called "information feedback based design" means design during which a large amount of information obtained during construction is used to provide guidance for the design and construction of the works, so as to achieve optimum tunnel structures. The determination of the displacement measurement criteria is one of the fundamental issues of the information feedback technology. On basis of the actual conditions of the sub sea tunnel on Xiamen East Passage, the article makes study on the displacement judgement criteria of the tunnel so as to facilitate the site application.
