To solve the inaccuracy problem caused by the two existing methods ( average end - area method and prismoidal method ) used for the calculation of roadway earthwork volume, this paper puts forward a new concept of the 3 - dimensional algorithm that takes all the roadway geometric design procedures as a kind of geometrical operation between the ground model ( original terrain model ) and the roadway model ( designed model ) under certain constraints, and then presents a complete 3 - dimensional algorithm of roadway earthwork volume as well as its executable computer program. the algorithm benefits from the re - triangulation technique of constrained delaunay triangulation ( cdt ), which can yield a true volume value theoretically. through a number of practical tests covering varied intervals between adjacent cross sections, it is proven to possess a higher accuracy compared with that of traditional methods. all the work involved in this paper indicates that the 3 - dimensional calculation of roadway earthwork volume is feasible, more accurate and should have further application in practice
針對目前廣泛使用的道路土方量計算方法平均斷面法和稜柱體法計算不準確的缺點，提出了三維土方量計算演算法的概念.該演算法以帶約束的狄羅尼三角化（ cdt ）為技術核心，認為所有道路幾何設計過程都是地面模型和道路（設計）模型進行幾何運算的結果.基於此，本文設計出相應的演算法步驟，同時完成了相應的軟體開發，使得該三維演算法能和傳統的方法進行對比.此外，結合工程實例，採用了不同的道路橫斷面間距對三維計算方法和傳統方法的誤差進行比較、分析.結果證明三維演算法具有更好的精度，該演算法可用於道路、場地平整等工程土方量計算 -
