摘要
土方量的测量与计算是建筑工程施工的一个重要步骤,土方测量的精度主要受实测地形数据精度与地貌模型的构造精度影响,较高的土方量测算精度是控制施工周期与施工成本的重要保证。论文首先对施工区域原始地面进行数据采集,再通过相应软件对土方量计算与分析,结论是工程土方量测算精度主要受碎部点采集精度和格网间距影响。
The measurement and calculation of earthwork is an important step in construction engineering.The accuracy of earthwork measurement is mainly affected by the accuracy of measured terrain data and the construction accuracy of geomorphic model.The high accuracy of earthwork measurement can help shorten the construction period and save the construction cost.In this paper,data collection is carried out on the original ground of the construction area,and the earthwork quantity is calculated and analyzed by the corresponding software.It is proved that the calculation accuracy of engineering earthwork quantity is mainly affected by the collection accuracy of broken parts and the spacing of grids.
