悬浮隧道工程研究方法及结构与设计方法研究

Study on research method,structure and design methodology of submerged floating tunnel engineering

悬浮隧道以往的研究特点可总结为项目研究或学术研究。文中提出第三类研究,即工程研究,并提出工程研究的方法、内容与模式。主要论点:1)工程研究的主线是结构;2)工程研究的本质是协同,包括设计与分析协同、分析理论与分析手段协同、数学模型与物理模型协同、以及对不同尺度物理模型与原型行为机理理解协同;3)工程研究采用攻关制,有助于突破资源与时间的限制,高效地创造永久价值;4)通过试验工程逐步完善工程研究方法,提出更多学术研究的方向、问题与需求。

The research on submerged floating tunnel in the past,can be generally regarded as project research or academic research.In this paper,we proposed the third type,the engineering research,of which the method,contents and work-mode were given.Main arguments are:1)the main thread of engineering study shall be the structure;2)the nature of engineering study are synchronizations of design and analysis,of theory and approach,of mathematical modelling and physical modelling,of understanding of structural behavior mechanism of physical models and prototypes in diffed scales;3)the problem-tacklingmode helps create more permanent value with less constraint on time and resource;4)by experimental project gradually perfect the engineering research method,and provide more academic research direction,question and need.
