城市综合管廊施工过程中的风险识别过滤研究

IDENTIFICATION AND FILTERING OF RISK IN PROCESS OF URBAN UTILITY TUNNEL CONSTRUCTION

城市综合管廊作为一个系统工程,其施工过程中的复杂性要求对其施工过程中的风险不能仅从一个视角或方面进行识别。一般的风险识别方法无法全面、系统地识别其风险因素。通过采用等级全息建模(HHM)方法对其施工过程中的风险进行全面、系统识别,对于识别出的风险因素,结合项目实例进行过滤分析,寻找出主要风险因素。可使决策者能够把有限的资源集中到高风险的防范中,也可为下一步开展风险评估和风险管理奠定基础。

As a system engineering, the complexity of the construction process of urban utility tunnel requires that the risk of the construction process can not be identified and analyzed from a perspective or aspect. General risk identification method can not identify the risk factors systematically and completely. By using the hierarchical holographic modeling （HHM）, identifying the risk factors of the construction process systematically and completely. Further, filtering and analysing the identifying risk factors, in order to find out the main risk factors. It not only can make the decision maker put the limited resources to the risk prevention, but also lay the foundation for the next step to carry out a risk assessment and risk management.
