【摘要】 地下空间开发已经成为世界各国的一种国策,而隧道工程在众多地下工程当中占据了非常重要的地位。虽然隧道工程在国内外都有飞速的发展,但在复杂的地质、水文和城市建筑环境下,地下构筑物具有太多的不稳定性,具有相当强的不可逆性,且建设成本较高,技术难度较大,施工工期较长,因此关于地下工程的各项研究在岩土工程研究领域仍然是紧迫、重要而且困难的课题。本文首先了解了国内外隧洞施工的发展情况,探讨了我国隧洞施工存在的问题。进而对本文输水洞工程提出了不仅需要对实际工程选择较好实施方案,还应该对其施工进行动态施工反馈控制的结论,从而基本确定了本文研究的方向和内容。本文针对大断面、埋深浅、穿越高速公路的输水洞具体工程进行了一系列的研究。首先针对具体工程提出的两种施工方案进行了有限元仿真模拟计算。接着以有限元仿真模拟计算的结果分析不同施工方案的特点,且综合其它多方面施工影响因素,引进模糊评判理论进行施工方案比选,确定出侧壁导坑施工方案为较优施工方案。又对侧壁导坑施工方案进行进一步有限元仿真模拟计算,研究得出最优的块体开挖顺序,并作了开挖土体参数对开挖影响的敏感性分析。然后根据施工反馈控制的特点,选择结合多Agent技术来构建隧洞施工反馈控制系统来指导施工。不仅介绍了Agent和多Agent系统(MAS)的思想,讨论了MAS对隧洞施工反馈控制系统的适应性;还对施工反馈控制系统进行了系统分析,设计了系统框架,构建子系统的结构和流程;最终从模块出发实现了MAS隧洞施工反馈控制系统,并通过实例调试了本系统。本文从设计优化方面提出了适合本工程的具体施工方案,并针对本工程采用多Agent技术构建的施工控制反馈系统能够指导具体施工,希望对其它隧道工程乃至地下工程的设计和施工有一定的借鉴作用。更多还原

【Abstract】 Underground space exploitation has already been a kind of national policy in many countries, the tunnel engineering plays a very important role in all underground engineering. Tunnel engineering is developed internal and overseas, each research is still a pressing, important and difficult problem in geotechnical engineering. Tunnel engineering costs higher,constructs more difficultly and lasts longer. Just because there are many strong instabilities and inconvertibility which can be occurred in complicated geology and hydrology and civic architectural environment.Firstly, the development of the internal and overseas tunnel engineering and then discusses the domestic problem about it is learned about by this paper. It suggests that we should select the satisfactory construction plan for the practice tunnel engineering and built the feedback control for the whole dynamic construction. So the research direction has been made.We do specific study on conveyance tunnel which is a big cross-section with superficial layer and through a speedway. First of all, this paper simulates the two plans of the tunnel engineering by using finite element method program. According to the calculation results of simulation, the trait of different construction plans had been analyzed. On the basis of Influence factors, the side wall pilot tunnel was confirmed to be the optimized plan by fuzzy evaluation theory method. Further, the optimum excavation subsequence is gain through calculating onside wall pilot tunnel plan by finite element method program and do the sensitivity analysis of soil parameter for affects on excavates. Then, in accordance with the feature of the engineering feedback control, the paper selects the multi-agent technology to make up the tunneling feedback control system. The mind of agent and multi-agent system is introduced, and the flexibility for the tunneling is also discussed. After analyzing the engineering feedback control system by the way of systems analysis, the paper designs the system frame, composes the structure and flow of the subsystem. Finally, the paper realizes the tunneling feedback control system by multi-agent system and debugs the application of the system by hypotheses example.The satisfactory construction plan has selected for the practice tunnel engineering, and the built feedback control system could guide for it. It is hoped that the paper can be referred by design and construction for other tunnel engineering and underground construction.更多还原
