摘　　要：扩容工程多在现有高速公路基础上扩建或改造,涉及对既有道路、桥梁、隧道、收费站等设施的保护和使用,以避免损坏或影响运行。扩容工程不仅加大了施工难度,还增加了额外的保护措施费用,加大了成本控制难度。对此,提出了高速公路扩容工程施工阶段预算管理及成本控制要点分析方法。先针对工程项目的开展环节,提取预算管理要素,并针对每个要素下的工程预算的影响机理,构建出预算管理指标体系;后引入关联因子,对构件成本与构件编码之间的关联度进行表征,并针对不同构件的计价信息,调整构件关注度;再以造价成本最低作为优化目标,构建出造价效益动态模型,并结合效益密度分布情况,输出最优效益分配策略;最后通过试验,对提出的方法进行了成本控制效果的检验。最终测试结果表明,采用本文提出的方法对工程项目进行成本控制时,项目单元的工程支出较低,具有较为理想的成本控制效果。Expansion projects often involve the expansion or renovation of existing highways,involving the protection and use of existing roads,bridges,tunnels,toll stations,and other facilities to avoid damage or impact on operation.The expansion project not only increases the difficulty of construction,but also incurs additional costs for protective measures,making cost control more challenging.A key analysis method for budget management and cost control during the construction phase of highway expansion projects has been proposed.Firstly,for the implementation process of engineering projects,budget management elements were sxtracted and a budget management indicator system was constructed based on the impact mechanism of engineering budgets under each element.Correlation factors were introduced to characterize the correlation between component costs and component codes,and component attention was adjusted based on pricing information for different components.Taking the lowest cost as the optimization objective,a dynamic model of cost benefit is constructed.In combination with the distribution of benefit density,the optimal benefit allocation strategy was output.Finally,the cost control effectiveness of the proposed method was tested through experiments.The final test results show that when using the method proposed in this paper for cost control of engineering projects,the engineering expenditure of project units is relatively low,which has a relatively ideal cost control effect.
