【摘要】 目前正在建设厦门东通道翔安海底隧道是我国大陆第一条海底隧道,与一般的公路隧道相比,其运营阶段的维修养护管理显得更为重要。海底隧道的维修养护是一项十分繁杂的工作,需要处理数据量庞大。因此,有必要开展对海底隧道维修养护数据库系统的研究。同时,由于地质条件,地形条件,气候条件,勘察、设计施工和运营等方面的影响,使海底隧道出现衬砌裂损、渗漏水、衬砌背后空洞、衬砌腐蚀等不同程度的病害,这些病害对隧道结构的安全存在巨大的影响。因此,对处于复杂条件下的海底隧道结构安全性评价进行研究成为另一重要的课题。本文以厦门翔安海底隧道为研究背景,对以上问题进行了研究。本论文的研究工作主要体现在一下几个方面:1.海底隧道维修养护数据库管理系统:海底隧道的维修养护涉及到很多的数据信息,包括设计、施工等基础资料信息,结构病害检测信息等等。因此十分有必要建立海底隧道维修养护数据库管理系统,这是整个维修养护计算机系统的基础。2.海底隧道结构安全性评价系统:阐述了模糊综合评价的基本原理、评价指标的选取、各指标权重的的确定等一系列问题。最终,初步建立了海底隧道结构安全性评价的模糊综合评价模型。3.计算机软件系统:阐述了系统的开发思路及结构设计,介绍了系统各个模块的功能及系统的工作流程。更多还原

【Abstract】 Xia’men east passage subsea tunnel under-construction, is the first subsea tunnel in mainland of China, compared to general highway tunnels, its maintenance and rehabilitation management is more important during operation. The subsea tunnel’s maintenance is a complex work and a lot of data need to be processed. So, it is necessary to carry out the research based on the database management system of the undersea tunnel’s maintenance. As the influence of geological conditions, terrain conditions, climatic conditions the investigation, designing, construction and running, etc. So that different extent diseases, such as lining split, leakage water, cavity behind lining, lining corrosion will appeared in subsea tunnel in service, and these diseases and endanger may have tremendous influence to the safety of tunnel structure in service. So, the research on the safety assessment of subsea tunnel in all kinds of complex circumstances and conditions is another important subject. The major work of this research is summarized as follows:1. Database Management of subsea tunnel’s maintenance: The maintenance of the subsea tunnel refers to much information, including designing data, construction data, disease detection data, etc. So, it is very necessary to establish database management for the subsea tunnel, and it is the base of the system.2. Structural Safety Assessment System to the subsea tunnel: This part describes the principle of fuzzy comprehensive evaluation, the selection of evaluation indexes, the determination of indexes weight and other problems. At last, it initially establishes the model of fuzzy comprehensive evaluation for the subsea tunnel’s structural safety assessment.3. Computer Software System: This part describes the development thought and framework of the computer system and it introduces the function of system modules and work flow of the system.更多还原
