| 摘 要： | 以路网所采集数据中的路面状况PCI值为控制指标,引用分层抽样和成数分层抽样方法,确定反映路网平均状态及路网状态分布所需调查的样本大小.在保证数据对路况真实状态反映的前提下,合理地选择调查样本并为路面管理系统提供可靠的依据.

| Abstract: | In all kinds of data collected from highway network,pavement condition index(PCI) is(taken) as a control index.Stratified sampling and portion stratified sampling are separately used to define the amount of samples that reflect the average status and status distributing of highway network.The data that reflect the real condition of highway network is reasonably sampled and used as a gist for pavement management system. |

| Keywords: | pavement management data collection scale of samples stratified sampling portion stratified sampling |
