一种复杂地形下的土方量计算方法及系统实现

A Calculation Method and System Implementation of Earthwork Volume Under Complex Terrain

针对当前工程项目中复杂地形中土方量计算低效、准确不足的问题,从应用需求出发,通过分析当前土方计算中的一些方法、工具、技术,在参考借鉴的基础上,利用测绘技术、三维可视化技术、互联网技术等,基于积分思想,设计了一套高效快捷、精度可控的土方量计算方法,即:以三维体为基底,对开挖填埋区域进行横纵向的剖分,以积分求和提升计算准确性。最后,基于Cesium三维开源框架进行系统实现。

This article focuses on the problem of low efficiency and insufficient accuracy in earthwork calculation in complex terrain in current engineering projects.Starting from application requirements,by analyzing some methods,tools,and technologies in earthwork calculation,based on reference,using surveying and mapping technology,3D visualization technology,internet technology,etc.,and based on integral thinking,a set of efficient,fast,and controllable accuracy earthwork calculation methods has been designed,namely,based on a three-dimensional body,the excavation and landfill area is divided horizontally and vertically to improve the accuracy of calculation by integrating and summing.Finally,the system implementation is based on the Cesium 3D open source framework.
