【摘要】：城市隧道及地下工程項目建設在當前注重效率的快節(jié)奏城市生活中對于舒緩交通壓力、節(jié)省地面空間、為人們提供更方便、快捷的交通方式等方面發(fā)揮了很大作用,除了在許多大城市建設使用外,現(xiàn)在也逐漸向中小型城市過渡,并形成了一定規(guī)模,結構建設在空間的深度、廣度上都有所延伸發(fā)展。由于城市隧道工程條件的復雜性和較大的施工難度使得這些項目導致了許多人員傷亡事故的慘痛悲劇的發(fā)生,同時,伴隨而來的巨大經(jīng)濟損失、生態(tài)環(huán)境污染和惡劣的社會影響在一定程度上也阻礙了其在人類社會今后的發(fā)展。本論文綜合考慮城市隧道工程建設的復雜條件,從預防重大工程事故和降低風險發(fā)生率的角度著手,借助西北地區(qū)城市隧道工程實例,在城市隧道全壽命風險管理體系方面做了大量的研究： (1)基于復雜的工程條件和當前的理論研究現(xiàn)狀,提出了具有普遍適用性的架構于項目建設過程、目標管理和風險管理模式上的三維RTP風險管理體系,并以兩個工程實例詳細說明了如何應用該體系對工程風險進行管理,從而實現(xiàn)進度、質(zhì)量、安全、投資的管理目標。 (2)建立了把靜態(tài)風險管理和動態(tài)風險管理有機結合的風險管理模式,建立了風險等級綜合評估標準,并根據(jù)風險的特點和誘因把風險歸為“人、機、料、法、環(huán)”五類對風險進行綜合評價。 (3)把計算機運用和風險分析預測結合起來提出了計算機輔助風險動態(tài)預測技術,并把虛擬建造可視化三維動畫技術和風險動態(tài)預測結合起來進行了探討,具有一定的意義。 (4)考慮當前風險評估方法的各自的特點,選用操作性強、實用范圍廣的多種綜合風險分析方法,搭載城市隧道全壽命風險管理體系,實現(xiàn)了項目總體風險和局部風險的管理,即能夠對工程風險進行宏觀控制又能夠對風險進行查找跟蹤,可以為類似工程提供一定參考。
[Abstract]:The construction of urban tunnels and underground engineering projects has played a great role in relieving traffic pressure, saving ground space and providing people with more convenient and fast transportation modes in the current fast-paced urban life, which pays attention to efficiency. In addition to the construction and use in many large cities, now also gradually transition to small and medium-sized cities, and formed a certain scale, structural construction in the depth of space, the breadth of the extension of the development. Due to the complexity of urban tunnel engineering conditions and the greater difficulty of construction, these projects have led to the tragic occurrence of many casualties, and at the same time, the accompanying huge economic losses. The ecological environment pollution and the bad social influence also hinder its future development in the human society to some extent. In this paper, considering the complex conditions of urban tunnel engineering construction, from the point of view of preventing major engineering accidents and reducing the incidence of risk, this paper makes use of the urban tunnel engineering examples in Northwest China. A great deal of research has been done on the risk management system of urban tunnel life: (1) based on the complex engineering conditions and the current theoretical research status, the universal applicability framework of the project construction process is put forward. Three dimensional RTP risk management system based on objective management and risk management mode, and two engineering examples are given to illustrate how to use this system to manage engineering risk in order to realize progress, quality and safety.
