摘要
通过对DTM法土方计算的模型建立、计算原理、结果检核、实践对照情况介绍,细述了DTM法土方计算编辑和检查的方法,并对其精度和稳定性作了探讨。
Based on the method of calculating the DTM earthwork calculation principle,model establishment,review,practice results contrast was introduced,and the calculation method of earthwork DTM editors and the method of the examination,and its accuracy and stability were discussed,concluding on practical application has certain directive significance.
