影响南水北调明渠工程建设的因素众多,如暴雨洪水、地质、意外事故等,各主要因素相互影响,且具有不确定性,不利于施工单位有效的进行风险管理。利用层次分析法和模糊优先关系排序决策对影响明渠风险的因素进行建模分析对比,得出的分析结果符合工程实际。通过两种方法的对比分析,为明渠风险管理提供借鉴,同时为工程实践提出可行的改进措施。
There are many factors affecting the construction of the open channel project of the South-to-North Water Diversion, such as storm floods, geology, accidents, etc. The major factors interact with each other and are of uncertainties, which is not conducive to the effective risk management of construction units. By using AHP and fuzzy priority ranking decision, the paper analyzes and compares the factors that affect the risk of open channel, and the analysis results are in line with the actual project. Through the comparative analysis of the two methods, it can provide reference for the management of open channel risk and propose feasible improvement measures for engineering practice.
