摘　　要：采用常规的二维方法计算工程量是相当烦琐复杂的工作,尤其是对基于复杂原始地形、不规则建筑物的工程量计算,选取不同计算方法得出的结果往往差异巨大。本文讨论采用建立三维设计方法,能快速建立三维原始地形模型和设计模型,高效地处理地形挖填并自动统计相应的工程量,同时可以立体直观地展示地形挖填的三维效果,显著提高设计效率和质量。Calculating quantities through employing usual 2D method is complicated,especially the quantities based on complex original terrain and irregular buildings.Also,the results generated by different methods vary greatly.This study investigates how 3D-design method efficiently builds 3D original terrain model and design models,deals with terrain cut-and-fill,and automatically calculates relevant quantities.Moreover,how the method helps to improve the design efficiency and quality through illustrating terrain cut-and-fill in 3D is discussed.
