【摘要】 公路工程项目是在复杂的自然和社会环境中进行露天作业的,其特点是建设周期长、投资多、技术要求高、内部结构复杂、外部联系广泛等。由此决定了在公路工程项目实施的过程中,存在着很多无法预计的不确定因素,而由这些不确定因素所带来的风险便会影响整个工程项目的实施。然而这些风险存在于工程项目当中又是不可避免的,如果不对它们采取任何控制措施,就会给业主和施工企业带来很大的损失。所以,风险就成为项目成败的关键。为避免其带给业主和施工企业的损失或减小影响,风险管理方面的研究就变得非常重要了。本文的研究对象是公路工程项目的风险管理,重点研究的是施工过程中的风险管理,从风险形成的因素分析、风险评价、风险模型、到风险防范对策等等。本文中还结合了重庆云阳南滨路公路工程施工的实际情况,运用风险评价方法对该工程施工风险建立风险模型,并根据专家调查法及专家评价法对风险模型进行定性分析,并根据专家反馈的定性数据进行定量数学计算,得出重庆云阳南滨路公路工程施工风险数据。并根据计算的结果给出了风险防范和改善的措施。本文最后给出了研究结论及公路施工风险管理方面的研究前景展望。更多还原

【Abstract】 Highway engineering projects is carried out in complex natural and social environment. Then often show the following characteristics such as long construction period, more investment, highly technical demanding, complicated internal structure, and extensively external contacts and so on. Therefore, there are many uncertain factors that cannot predict in the process of implementation which often affected the smooth implementation of project. There are many risks existing in highway projects. If we treat with these risks improperly, the owners of highway engineering and construction enterprises will suffer huge loss. Accordingly, it is risk that decided a highway project is successful or not. So it is rather necessary to research on risk management about highway project in order to avoid or reduce losses by the owners of highway engineering and construction enterprises.Taking risk of highway project management as study object, this paper researches on the whole cycle of risk management in highway construction project, especially in construction phase. It mainly includes the analysis of risk factor, risk assessment, risk models, and risk prevention measures and so on. Combined with Chongqing Yunyang Nanbin highway construction work, this paper establishes the construction risk model by risk assessment methods and analyzes the risk model qualitatively by expert survey and evaluation method. Then it gives a mathematical calculation according to the feedback data from experts and it educes the risk data of Chongqing Yunyang Nanbin highway construction. After that, it presents the risk prevention and mitigation measures according to calculation results. Finally, this paper elicits the conclusion and expectation of the risk management in highway construction.更多还原
