摘　　要：为了便于构建市政桥梁工程的投资估算模型,解决市政桥梁工程投资估算精确度不高的问题,筛选出市政桥梁工程的投资估算模型的影响因子,有针对性地优化市政桥梁工程的投资估算模型,改善市政桥梁工程的投资估算工作。以空心板梁桥为研究对象,采用信息沉淀法对相关文献资料进行分析,获取影响市政桥梁工程投资模型的初始影响因子集;并通过对调查问卷收集的数据进行隶属度分析,筛选出对市政桥梁工程投资模型有显著影响的10个可行性影响因子。In order to build investment estimation model of municipal bridge projects and to solve the problem of inaccuracy of municipal bridge project investment estimate,this paper screens the impact factors of municipal bridge project investment estimation model.So it can be targeted to optimize investment estimation model of municipal bridge projects,and improve the work on investment estimate of municipal bridge project.It regards hollow plate girder bridge as the research object,and obtains the initial set of impact factors affecting municipal bridge project investment model by analyzing the relevant literature using the method of information precipitation.10 feasibility impact factors are screened out by analyzing the data collected by the questionnaire with membership degree analysis.
