为提高路面病害治理效率,将GIS空间分析理论和方法运用到路面病害数据管理中.根据路面病害系统的设计目标,进行功能设计和数据库设计,运用可视化语言VB和MAPX控件,建立基于MAPX的路面病害数据库(PDMS).研究结果表明:该系统实现了图形与数据的双向快速查询,并直观的在地图上或者以专题地图的形式为用户提供历史病害发生的空间位置与属性位置,方便了检索查询病害历史数据;还为用户提供采集和保存多样形式病害数据的功能,为路面养护和使用寿命评估提供丰富的数据来源.
In order to improve the efficiency of pavement disease management, GIS spatial analysis theory and method are applied to pavement disease data management.According to the design goal of pavement disease system, functional design and database design are carried out, and visual language VB and MAPX control are used to establish MAPX-based pavement (PDMS) .The research results show that the system can realize two-way quick query between graphics and data, and intuitively provide the user with the spatial position and the attribute location of the historical disease in the form of a thematic map or the thematic map to facilitate the retrieval Querying disease history data, providing users with the functions of collecting and storing disease data in various forms, and providing rich data sources for pavement maintenance and life assessment.
