摘 要:高速公路日常养护费用投入与路况条件息息相关,探索二者之间的关系有利于提高养护资金的使用效率。本文通过定性分析与多元线性回归分析相结合的方式,依托某高速公路公司管理的若干条高速公路历史数据,研究高速公路沥青路面日常养护费用和路面破损状况指数PCI、路面技术状况指数MQI的定量关系。结果表明:为使PCI提升1%,日常养护费用投入需增加8.4%;基于公路各分项技术指标的定量关系,在其他分项指标技术状况保持不变的情况下,为使MQI提升1个单位分值,路面日常养护费用需增加■。The investment in daily maintenance costs of highways is closely related to road conditions,and exploring the relationship between the two is beneficial for improving the efficiency of using maintenance funds.This article combines qualitative analysis and multiple linear regression analysis,relying on historical data of several highways managed by a certain highway company,to study the quantitative relationship between daily maintenance costs of asphalt pavement on highways,pavement damage index PCI,and pavement technical condition index MQI.The results indicate that in order to increase PCI by 1%,the daily maintenance cost investment needs to be increased by 8.4%.Based on the quantitative relationship between various sub technical indicators of the highway,while keeping the technical status of other sub indicators unchanged,in order to increase the MQI by 1 unit score,the daily maintenance cost of the road surface needs to be increased by■.
关 键 词:日常养护费用 路面破损状况指数PCI 路面技术状况指数MQI 多元回归
