中国典型道路谱数据库的开发与应用

回顾了我国道路谱和路面不平度的数据测量与分析、数据库建设与应用的研究现状，介绍了自主开发的高精度道路谱测量系统的数据测量原理和试验方法。在此基础上从典型地区和典型路段的选择、全国范围典型路段的采集和测量、海量道路谱采集数据的批量自动分析计算、道路谱数据库的整体架构和系统组成，以及数据库的具体实现和维护等几个方面阐述了中国典型基础道路谱数据库的开发过程。另外从道路谱数据库在汽车工程领域的设计开发和公路行业中的应用进行了探讨，最后对中国典型道路谱数据库的推广应用进行了展望。

Development and application of typical road spectrum database in China

It’s reviewed that the research progresses of the measurement methods and database development of road spectrum and road roughness in recent years in China. A new high precision road spectrum measurement system is presented and its measurement principle and testing method are introduced. Based on the measurement system, these is a new typical road spectrum database has been built which including many steps, such as typical cities and typical roads selected, typical roads surface data acquired in total China, massive original data automatic processed, overall framework of database established, road spectrum database realized and applied. In addition, the road spectrum database are applied in automobile engineering and highway departments. In the end, the using fields of road spectrum database are summarized and its prospect is evaluated.
