本文结合工程实例，介绍了几种常用的土方计算方法，并利用CASS软件计算了两期间土方差值。提出了通过设定较低平场标高来计算两期间土方差值的方法，虽然通过实例计算，验证了在两期间范围测量存在较大误差的情况下，此种方法并不适用，但分析了具体原因，提出了解决办法，为以后优化土方计算方法提出了思路。
本文結閤工程實例，介紹瞭幾種常用的土方計算方法，併利用CASS軟件計算瞭兩期間土方差值。提齣瞭通過設定較低平場標高來計算兩期間土方差值的方法，雖然通過實例計算，驗證瞭在兩期間範圍測量存在較大誤差的情況下，此種方法併不適用，但分析瞭具體原因，提齣瞭解決辦法，為以後優化土方計算方法提齣瞭思路。

Combining engineering examples , several common earth volume calculation methods are introduced and the difference between twice earthworks is calculated by CASS software in this paper .The method by setting a lower elevation of the flat‐field to calculate the difference between twice earthworks is proposed in this paper .Although an example is given to verify this method is not applicable in the case there is a big error during range measurement ,the specific reason is analysed and the solution is proposed .The idea is pro‐posed for optimizing the method of earth volume calculation .
