工程土方计量系统研究与实现
摘要
在工程项目前期土建设计过程中,开发一套高精度、易操作的工程土方计量系统具有重要意义。本文结合地理信息系统技术、计算机技术和数据库技术等技术手段,采用C#语言对ArcGIS平台进行二次开发,对TIN算法进行改进,并研发了工程土方计量系统。通过与南方CASS和ArcGIS传统的TIN算法进行对比分析得出:采用本系统计算出的土方量精度较高,大大提高了工程土方计量内业数据处理的效率,精简了数据处理流程。
In the process of civil engineering design in the early stage,it is of great significance to develop a set of engineering earthwork measurement system with high precision and easy operation.In this paper,combined with geographic information system technology,computer technology and database technology and other technical means,using C# language ArcGIS platform for secondary development,improvement of TIN algorithm,and the development of engineering earthwork measurement system.Through the comparison and analysis with the traditional TIN algorithm of CASS and ArcGIS in south China,it is concluded that the precision of earthwork calculated by this system is relatively high,which greatly improves the efficiency of the data processing of engineering earthwork measurement and simplifies the data processing process.
