摘　　要：针对目前绘制断面图效率较低的问题,提出一种高效获取所有断面线附近指定范围内的高程点数据,并将断面数据自动转换至项目所需的数据格式,然后批量绘图的算法。应用AutoCAD二次开发语言编制针对性的数据自动化处理软件,实现批量展绘测量点,绘制断面线,标注里程桩号,提取断面数据,并绘制断面图,有效提高了自动化程度。实际结果表明,该软件计算结果正确、可靠,运行简便、高效、稳定,切实满足了项目生产中的实际需求,提高了作业的生产效率和标准化水平。Aiming at the problem of low efficiency in drawing cross-sectional maps at present,a high-efficiency algorithm is proposed to obtain elevation point data within the specified range near all cross-sectional lines,automatically convert cross-sectional data to the required data format for the project,and then plot in batches.The application of AutoCAD secondary development language to develop targeted data automation processing software achieves the goals such as batch drawing of measurement points,drawing of section lines,marking of mileage and pile numbers,extraction of section data,and drawing of section maps,effectively improves the level of automation.The results indicate that the software's calculation results are correct and reliable.The simple,efficient,and stable operation effectively meets the actual needs of project production and improves the production efficiency and standardization level of operations.
