摘要
随机测定地块不同点的坐标和高差,每3个相邻点构成一个三角形区段,计算3个点的相对平均标高值,即该测区的平均高程。与常规的方格网土方工程量计算相比,该法较粗略,但在抢险救灾,急难危重时刻,作为大致估算,是一种有效的定量化计算手段。
Coordinate and height difference at different points are measured randomly. Every three adjacent points forms a triangle sector. The relative average elevation is the average elevation of the sector. It＇s a little rough compared to conventional square gird earthwork quantity calculation. But it＇s an effective quantitative calculation method to roughly estimate the earthwork amount in emergency rescue and disaster relief.
