摘　　要：当前公路设计中基于CAD的公路设计软件如纬地、海地、鸿业、路线大师等,均采用平均面积法计算土石方工程量,而在公路施工建设过程中,局部深沟或突兀山嘴的路段,土石方工程量存在不小的误差。采用三维GIS表面分析模型,对局部路段的土石方工程量进行分析计算,结果证明该方法对公路建设过程中的填挖土石方工程量校核具有指导意义。The current highway design software based on CAD all use average area method to calculate the amount of earthwork,such as Hint Soft,Hard,Hong Ye Road,Route Master,etc.However,in the process of road construction and engineering,part gorge or abrupt spur region,there are many errors in the amount of earthwork and stonework.This article uses a three-dimensional GIS surface analysis model to analyze and calculate the amount of earthwork and stonework for local sections.The result proves that this method has guiding significance for the checking of the filling and excavating earthwork quantity in the process of highway construction.
