Research on Life Cycle Cost Prediction of Expressway Based on Fuzzy Cluster Analysis
The integration of life-cycle cost management and construction,management and maintenance is beneficial to improve the investment benefit and social benefit of expressway,and cost prediction is the basis of optimization of design and maintenance scheme.In the case of limited samples of major and medium-sized repairs,the fuzzy cluster analysis method is applied to predict the cost of major and medium-sized repairs of expressway subgrade,pavement and structures in combination with the characteristic indexes of expressway special projects.The life cycle cost model is established,and the design schemes are compared and selected according to the life cycle costs such as construction cost,maintenance cost,user cost and environmental cost,and an example is analyzed to avoid the defects of high later maintenance and operation cost caused by scheme selection based on simple construction cost minimum and qualitative analysis.The research results have a guiding role in design scheme optimization and integration of construction,management and maintenance.
