土方量快速计算本文介绍的方法不需要展绘横断面图，直接从地形图或碎部测量的平面图上量取特征点坐标，然后计算出断面面积的体积。工作原理：（１）多边形的面积Ｓ，见图。多边形面积图Ｓ＝１２ｘ１ｙ１ｘ２ｙ２＋ｘ２ｙ２ｘ３ｙ３＋……＋ｘｎｙｎｘｎ＋１ｙｎ＋１｛｝...
Rapid Calculation of Earthwork Volume The method described in this paper does not require the display of cross-sectional maps. Measure the coordinates of the feature points directly from the topographic map or the ground planes on the ground, and then calculate the volume of the section area. How it works: (1) The polygon area S, see figure. Polygon area chart S=12x1y1x2y2+x2y2x3y3+......+xnynxn+1yn+1{}...
