摘要
在工程建设中,经常要进行场地整平或改造成设计坡度的斜面,由此产生的土方量大小与工程投资直接相关,因此准确、快速地计算土方量对开展规划设计、控制总投资及分配资金具有重要意义。本文分析比较了两种常用土方计算软件,用相对成熟精确的方格网法,对同一块场地进行土方计算,比较两者的操作性、运算速度和精度,分析其相对优缺点。
The ground was frequently leveled or altered into a designed slope in constructing, and the earthwork calculation is directly related to the investment, so how to calculate the amount of earthwork accurately and quickly influences the planning and design of the eonstruction. This paper compares two types of commonly used software of earthwork calculation, calculates the same earthwork adopting the grid network method, and finally analyses their relative advantages and disadvantages.
