【摘要】：广东省天然气管网一期工程是广东省重点能源建设项目,是全省一张网、政府统筹对天然气资源进行高效利用重要组成部分。西江盾构穿越工程是整个省管网一期工程中的重大控制性工程之一,其意义非凡,将直接影响到能否按期向肇庆地区供应清洁、高效的天然气资源。由于广东地区地质条件复杂,在如此地质条件下进行盾构施工,其风险不言而喻。本文主要从风险管理的角度出发,定性和定量地对工程中的主要风险进行分析和评估,主要包括以下几个方面：(1)在查阅相关资料的基础上,分析西江盾构工程项目的主要特点,并在此基础上提出该工程建设过程中的难点,据此引申出西江盾构穿越项目施工过程中风险管理的重要性。(2)采用资料分析法以及专家调查法对西江盾构穿越工程项目进行风险识别,指出西江穿越砂岩、粉质粘土以及砂所共同形成的复杂地质结构时的风险环境以及致险因子,此外,还提出了可能会出现在西江盾构隧道施工过程中的一系列风险。(3)采用风险识别方法确定主要施工风险之后,引入R=P×C模型和模糊综合评价相结合的分析方法,确定西江盾构主要施工风险的等级。(4)从风险产生的机理入手,结合省管网一期工程西江盾构隧道施工的过程,从风险的孕险环境和致险因子等方面提出了详细的解决措施。(5)提出了西江盾构隧道施工风险对策,并设计了应急救援预案和应急救援系统。
[Abstract]:The first phase of the natural gas pipeline network in Guangdong Province is a key energy construction project in Guangdong Province and a network of the whole province. The government coordinates the effective utilization of natural gas resources as an important part. Xijiang shield tunneling project is one of the major control projects in the first phase of the provincial pipeline network. Its significance is extraordinary and it will directly affect whether or not clean and efficient natural gas resources can be supplied to Zhaoqing area on schedule. Because of the complex geological conditions in Guangdong area, the risk of shield construction under such geological conditions is self-evident. This paper analyzes and evaluates the main risks in the project qualitatively and quantitatively from the point of view of risk management, including the following aspects: (1) on the basis of consulting relevant data, Based on the analysis of the main characteristics of the Xijiang shield engineering project, the difficulties in the construction process of the project are put forward. The importance of risk management in the construction process of Xijiang Shield Crossing Project is derived. (2) the risk identification of Xijiang Shield Crossing Project is carried out by using data analysis method and expert investigation method, and it is pointed out that the Xijiang River Crossing Sandstone, The risk environment and risk factors for the complex geological structure formed by silty clay and sand, A series of risks which may appear in the construction process of Xijiang shield tunnel are put forward. (3) after the risk identification method is used to determine the main construction risks, the RPXC model and the fuzzy comprehensive evaluation are introduced. Determine the grade of main construction risk of Xijiang shield. (4) starting from the mechanism of risk generation, combining with the construction process of Xijiang shield tunnel in the first phase of provincial pipeline network project, Detailed measures are put forward from the aspects of risk environment and risk factors. (5) the construction risk countermeasures of Xijiang shield tunnel are put forward and the emergency rescue plan and emergency rescue system are designed.
