基于CAD二次开发的公路养护辅助设计系统

Highway maintenance aided design system based on secondary development of CAD

公路养护设计基于公路技术状况检测数据进行,运用到的数据项多、数据量大,为解决数据处理、分析、展示等工作量大的问题,提高公路养护设计自动化、智能化水平,采用VBA工具对浩辰CAD进行了二次开发。二次开发程序可以读取原始数据,自动绘制路面病害分布图,处治段落分布图等,并根据处治段落和方案计算路基、路面、交安养护工程量和费用,提高设计效率和质量。

Highway maintenance design is based on the detection data of highway technical conditions.The data items and data quantity used in highway pavement maintenance design are large.In order to solve the problem of large data processing,analysis and display workload,the paper uses VBA tool to develop Haochen CAD secondary.The secondary development program can read the original data,automatically draw the pavement disease distributionmap and treatment section distributionmap.The maintenance quantities shall be calculated according to the treatment section and scheme.So as to improve the design efficiency and quality.
