摘　　要：土方量的计算作为建筑工程设计与施工的一个重要步骤,其精确性直接关系到工程的费用概算及方案优选。通过采用地统计普通克里金法得到青海同仁330 kV变电站站址高程预测图,并通过预测值与实际值的相关性分析验证该高程预测模型的可行性与适用性;然后基于ArcGIS中的3D Analyst Tools工具,生成原始地表和设计标高面TIN模型,并采用Cut/Fill工具计算站区内土地平整的挖填方量。该方法可真实地反映站区地形信息,实现三维可视化,为复杂地形的土方量计算提供新的方法和思路。The calculation of earthwork is an important step in the design and construction of building engineering,and its accuracy is directly related to the project cost estimate and scheme optimization.In this paper,the elevation forecast map of 330 kV substation in Tongren,Qinghai Province is obtained by using geostatistical ordinary kriging method,and the feasibility and applicability of the elevation forecast model are verified by the correlation analysis between the forecast value and the actual value Then,based on the 3D Analyst Tools tool in Arcgis,the TIN model of original surface and design elevation is generated,and the Cut/Fill tool is used to calculate the volume of the excavation and Fill of the land leveling in the station area.This method can reflect the terrain information of station truly,realize 3D visualization,and provide a new method and thought for the calculation of earthwork in complex terrain.
