目前,生命周期成本分析(Life Cycle Cost Analysis,LCCA)和生命周期环境评价(Life Cycle Assessment,LCA)方法常用于评估路面在全生命周期范围内的经济和环境影响.然而,路面LCCA和LCA方法在应用过程中存在数据量大、数据类别多造成评价过程烦琐的问题.针对此类问题,部分学者尝试将BIM(Building Information Modeling)与LCCA和LCA方法相结合以优化评价流程.在路面领域,LCCA和LCA与BIM相结合的研究还处于初级阶段,缺少对其相关研究成果的总结.因此,该文通过对路面LCCA、LCA、LCCA-LCA及与BIM相结合的研究进行归纳总结,探究其存在的问题与面临的挑战.研究发现:BIM的应用能够优化LCCA和LCA过程,实现设计与评价的动态协同.但目前存在集成化程度不高、建模软件与评价软件之间统一数据格式标准的欠缺等问题,因此阻碍了其应用发展.
Review on LCCA and LCA Methods for Pavement Based on BIM
Currently,life cycle cost analysis(LCCA)and life cycle assessment(LCA)methods are commonly used to assess the economic and environmental impacts of pavement during the whole life cycle.However,there are drawbacks in the application of LCCA and LCA methods,such as a large amount of data and multiple data categories,which lead to a tedious evaluation process.In view of this,some scholars have tried to combine building information modeling(BIM)with LCCA and LCA methods to optimize the evaluation process.In the pavement field,the combination of LCCA and LCA with BIM is still in its infancy,lacking a summary of relevant research results.Therefore,this paper summarized the research on LCCA,LCA,and LCCA-LCA methods for pavement,as well as their combination with BIM to explore the existing problems and challenges.It is found that the application of BIM can optimize the LCCA and LCA processes and realize the dynamic coordination of design and evaluation.However,the low integration degree and the lack of unified data format standards between modeling software and evaluation software hinder the application and development of BIM.
