摘　　要：在水利工程前期规划与设计中,土方量的计算方法不仅影响到方案布置,而且其计算结果还会直接影响到工程成本预算与项目组织问题。基于GIS技术计算工程土方量的方法是利用DEM提供的高程信息,结合ArcGIS平台的分析工具实现土方量快速、高效的计算,尤其是对于数据量大的计算尤为明显。针对传统DEM法计算工程土方量过程中存在重复作业、自动化程度低等问题,该文在DEM法基础上,在ArcGIS平台中基于Python语言结合特定的ArcPy函数编写一种工作流模式的应用工具,实现工程土方量计算的自动化处理。通过优化后的计算方法对洪泽湖(泗洪县)退圩环湖工程中清退圩埂的土方量进行计算和分析,并得到可靠的计算结果,为水利工程提供一种全新的土方算量解决方案。In the early planning and design of water conservancy project,the calculation method of earthwork not only affects the scheme layout,but also directly affects the project cost budget and project organization.The method of calculating engineering earthwork based on GIS technology is to use the elevation information provided by DEM,combined with the analysis tools of ArcGIS platform to achieve fast and efficient earthwork calculation,especially for the calculation of large amount of data.In order to solve the problems of repeated work and low automation in the process of calculating engineering earthwork by traditional DEM method,on the basis of DEM method,this paper compiles an application tool of workflow pattern based on Python language and specific ArcPy function in ArcGIS platform to realize the automatic processing of engineering earthwork calculation.Through the optimized calculation method,the earthwork volume of the retreating polder ridge in the project around Hongze Lake(Sihong County)is calculated and analyzed,and reliable calculation results are obtained,which provides a new earthwork calculation solution for water conservancy projects.
