为了量化比较水泥混凝土路面在全寿命周期内基于经验和基于分析的两种大修策略的效益差别,该文采用了美国佐治亚州水泥混凝土路面上采集的近50年的路况数据,建立了路面服务寿命的Cox比例风险模型,基于3个评估指标——总养护费用(LCC)、分析期内的平均路况(FI_(AVG))和养护效益(FI_(AVG)×LCC),评估了某典型水泥混凝土路面结构的两种大修策略在50年分析期内的养护效益。 To quantify the difference in benefit between two experience-based and analysis-based overhaul strategies over the entire life cycle of a cement concrete pavement, this article uses nearly 50 years of road profile data collected on a cement concrete pavement in Georgia, United States to establish pavement service life Cox proportional hazards model was used to assess the impact of a typical cement concrete (CAG) on the basis of three assessment indicators - total maintenance cost (LCC), average road conditions during the analysis period (AVG) and conservation effectiveness Pavement structure of the two overhaul strategies in the 50-year analysis of conservation benefits.
