麗攀高速公路項目施工安全風(fēng)險管理的研究

發(fā)布時間:2019-05-10 00:23
【摘要】:隨著我國社會經(jīng)濟的跨越式進步,私家汽車保有量急劇上升,物流的快速增長和運輸需求的繼續(xù)增加,對高速公路的需求量越來越大。高速公路專供汽車高速、安全、舒適行駛,是衡量一個國家道路交通現(xiàn)代化水平的重要標(biāo)志,同時也是國家經(jīng)濟發(fā)展要求的必然產(chǎn)物。在施工過程中必須對整個過程做到安全、規(guī)范、具有實效性的管理,這是整個施工過程中非常重要的風(fēng)險管理機制,這也被稱作項目風(fēng)險安全管理。在施工前對施工對象進行風(fēng)險評估,具體了解整個工程的風(fēng)險情況,并判別出風(fēng)險大小,根據(jù)具體的風(fēng)險指數(shù)來制定相應(yīng)的應(yīng)對措施,盡可能的使整個工程的風(fēng)險指數(shù)降到最低,保證工程能夠安全施工。 本文梳理了國內(nèi)外關(guān)于高速公路風(fēng)險管理的研究成果,系統(tǒng)闡述總結(jié)了高速公路施工安全風(fēng)險管理的相關(guān)理論,總結(jié)了工程項目管理概念、特征、項目管理任務(wù)和類型,并定義了公路工程施工風(fēng)險,厘清了公路工程施工安全風(fēng)險發(fā)生的機理,歸納了風(fēng)險管理的流程。 本文在掌握麗攀高速公路的概況、水文地質(zhì)情況、高速公路施工的重點和難點工程基礎(chǔ)上,識別了麗攀高速公路風(fēng)險因素;分別對麗攀高速公路的路基工程、橋梁工程、隧道工程等主要分項工程的風(fēng)險進行了分析:系統(tǒng)分析了路基土石方工程的挖土方、挖石方,路基坡面防護以及路基填方等項目中的施工工藝和作業(yè)工種情況,分析其可能存在風(fēng)險因素;系統(tǒng)分析了麗攀高速公路中橋梁基礎(chǔ)、下部構(gòu)造和上部構(gòu)造的施工以及隧道工程地質(zhì)條件、隧道通風(fēng)、隧道供電和給排水的施工過程及可能存在風(fēng)險因素;運用模糊綜合評價方法,從人的因素、物的因素、環(huán)境因素和組織因素四個方面評估了麗攀高速公路施工安全風(fēng)險。根據(jù)評估的結(jié)果,本文最后制定了路基土石方、橋梁工程和隧道工程施工過程的應(yīng)對舉措。
[Abstract]:With the leap-forward progress of social economy in our country, the number of private cars has risen sharply, the rapid growth of logistics and the continuous increase of transportation demand, the demand for expressway is increasing. Highway is designed for high speed, safe and comfortable driving, which is an important symbol to measure the modernization level of road traffic in a country, and it is also the inevitable product of the requirements of national economic development. In the construction process, we must be safe, standardized and effective management of the whole process, which is a very important risk management mechanism in the whole construction process, which is also called project risk safety management. Before construction, the risk assessment of the construction object is carried out, the risk situation of the whole project is understood concretely, and the risk size is identified, and the corresponding countermeasures are formulated according to the specific risk index. As far as possible, the risk index of the whole project can be minimized to ensure the safe construction of the project. This paper combs the research results of highway risk management at home and abroad, systematically expounds and summarizes the relevant theories of highway construction safety risk management, and summarizes the concept, characteristics, project management tasks and types of engineering project management. The construction risk of highway engineering is defined, the mechanism of safety risk of highway engineering construction is clarified, and the process of risk management is summarized. On the basis of mastering the general situation of Lipan Expressway, hydrogeological conditions, the key and difficult projects of expressway construction, this paper identifies the risk factors of Lipan Expressway. The risk of subgrade engineering, bridge engineering, tunnel engineering and other main sub-projects of Lipan Expressway is analyzed respectively. The earthwork and rock excavation of subgrade earthwork are systematically analyzed. The construction technology and work types in subgrade slope protection and subgrade filling projects are analyzed, and the possible risk factors are analyzed. The construction of bridge foundation, lower structure and superstructure, as well as the engineering geological conditions of tunnel, tunnel ventilation, tunnel power supply and drainage construction process and possible risk factors are systematically analyzed. The construction safety risk of Lipan Expressway is evaluated from four aspects: human factor, material factor, environmental factor and organizational factor by using fuzzy comprehensive evaluation method. According to the results of the evaluation, the countermeasures of subgrade earthwork, bridge engineering and tunnel construction process are worked out at the end of this paper.
