摘要
主要介绍了方格网法、断面法、等高线法、DTM法四种土方计算方法的计算原理,利用CASS 7.0软件的土方计算辅助计算模块中提供的方格网法、断面法、等高线法、DTM法进行计算实现,在算例分析的基础上,对四种方法的计算精度、适用范围、优缺点进行分析比较,并对土方计算的发展前景进行展望。
The calculation principle of square grid, section method, contour method and DTM method are mainly introduced in this paper. The computational implementation is obtained by the square grid, section method, contour method and DTM method provided by auxiliary calculation module of earthwork calculation in CASS7.0. Based on the analysis of examples, the calculation accuracy, application scope, advantage and disadvantage are analyzed and compared. Finally, the prospects of earthwork calculation are discussed.
