Description

In highway projects, balancing cut-fill is an important way to minimize economic payout. As the result, cut-fill calculation becomes a necessary work to the highway designer. Traditionally, cut-fill planning is not only a slow, laborious work, but also one of the problems in the feasibility analysis. With the large-scale products of Digital Elevation Model (DEM) shared up and put to use, automatic analysis for cut-fill projects is provided with reliable authenticity. This paper tries to develop a cut-fill algorithm on the basis of ARC/INFO GRID on the condition of the unknown hypsography resulted from the cut-fill diffusion model, provided with pre-cut-fill DEM and road coverage, engineering side-slope, road height and width. The aim of this paper is to propose the algorithm to calculate excavation- amount, fill-amount, and simulate the post-cut-filled DEM when the supposed cut-fill is done. This algorithm is feasible based on current GIS software, can save a lot time for the highway designers and offer a considerable cut-fill designing.<br>
