| Abstract: | Cut/Fill earthwork is indispensable in construction project,the purpose of which is to make plane position and elevation satisfy the design of building.Therefore,we construct the digital elevation model(DEM) of triangulated irregular network(TIN) to improve the calculated precision of the earthwork.The algorithm simplifies the model of calculation,which is more convenient for computer automation. |
