The paper introduces the earth volume calculation principle, method and procedure of square grid method, takes Huozhaotun village in Liangerzhuang town of Qiu county as an example, cai-ries out auxiliary calculation of land evening engineering earth volume with CASST. 0. Through comparing with actual engineering, results show that calculation result is similar with actual engineering, which can meet the project demand.%首先介绍了方格网法进行土方量计算的原理、方法与步骤,然后以邱县梁二庄乡霍赵屯村为例,借助CASS7.0软件对土地平整工程土方量进行了辅助计算。经过与实际工程的对比分析发现,计算结果与实际工程相差不大,能够满足项目需要。
