【摘要】：近几年来,经济的迅速发展,推动城市基础设施建设,提升城市功能,地铁建设迎来发展的高峰。因此开展地下隧道工程施工技术研究和风险分析,也是当今形式下地铁建设的需要。地铁隧道施工时,受地质情况、施工项目周边的环境情况影响很大,尤其地上地下既有建筑物、管线等其他许多不确定性因素,会对工程项目的顺利实施产生风险,这就要求必须全面掌握地铁隧道施工技术,尤其是施工工法的选择,施工风险研究等,有利施工的安全性,避免安全事故的发生。并且当今爆破施工是隧道掘进的主要方法,因此必须加强对隧道爆破技术研究,控制爆破振动,合理进行爆破方案设计,加强监测从而将风险控制在预期的目标内,减小爆破施工所带来的安全影响。本文结合大连地铁施工情况,对浅埋隧道施工技术研究、风险分析,尤其爆破振动控制及爆破施工安全管理等问题作深入分析研究,并根据爆破施工特点,运用风险管理理论,系统工程学等,明确施工的主要风险源,通过层次分析法,建立风险评价层次结构,构建CIM模型评估体系,取得很好效果。运用爆破减振技术,顺利实现地铁隧道施工。本文的研究涉及地铁工程项目的设计、施工和管理等几个重要方面,形成系统化的理论,希望能为类似工程项目提供借鉴和参考。
[Abstract]:In recent years, with the rapid development of economy, urban infrastructure construction and urban function have been promoted, and subway construction has ushered in the peak of development. Therefore, the underground tunnel construction technology research and risk analysis are also the needs of subway construction. During the construction of the subway tunnel, the surrounding environment of the construction project is greatly affected by the geological conditions, especially many other uncertain factors such as existing buildings, pipelines and other uncertainties above ground and underground, which will bring risks to the smooth implementation of the project. Therefore, it is necessary to master the construction technology of subway tunnel, especially the selection of construction method, the study of construction risk and so on, which will benefit the safety of construction and avoid the occurrence of safety accidents. At present, blasting construction is the main method of tunnel excavation, so it is necessary to strengthen the study of tunnel blasting technology, control blasting vibration, reasonably carry out blasting scheme design, strengthen monitoring so as to control the risk within the expected target. Reduce the safety impact of blasting construction. Based on the construction situation of Dalian Metro, this paper makes a deep analysis and study on the construction technology, risk analysis, especially blasting vibration control and safety management of blasting construction, and applies the theory of risk management according to the characteristics of blasting construction. System engineering and so on, the main risk sources of construction are defined, and the hierarchical structure of risk evaluation is established by AHP, and the evaluation system of CIM model is constructed, and good results are obtained. The construction of subway tunnel is realized successfully by using blasting vibration reduction technology. The research in this paper involves several important aspects such as design, construction and management of subway engineering projects, and forms a systematic theory, hoping to provide reference and reference for similar engineering projects.
