Submerged floating tunnel overall structural behavior mechanism experimental study 2:Detailed design

在“概念设计”的基础上介绍了悬浮隧道整体结构行为机理试验的详细设计,旨在细化设计方案,指导机理试验的开展。基于重力相似准则同时考虑弹性相似方法,详述了悬浮隧道模型制作及试验方案的设计,主要包含模型制作与安装、试验物理量测量布置以及外部水动力环境加载等的具体实现过程。文章首次揭露机理试验详细设计内容,明确试验结果与实际工程的相关性,为机理试验开展提供具体实施方案。

On the basis of"conceptual design",we introduced the detailed design of the submerged floating tunnel overall structural behavior mechanism tests,aiming at refining the design scheme and guiding the development of the mechanism test.Based on the gravity similarity criterion and considering the elastic similarity method,we described in detail the design of the model making and test scheme of the submerged floating tunnel,including the concrete implementation process of model making and installation,test physical quantity measurement arrangement and external hydrodynamic environment loading.In this paper,the detailed design contents of the mechanism test are revealed for the first time,and the correlation between the test results and the actual project is clarified,so as to provide a specific implementation plan for the mechanism test.
