ABSTRACT
The earthwork volume calculation based on three-dimensional design can overcome shortcomings of fats methods. Firstly, it takes only 1~2 sec to complete earthwork calculation, which helps avoid cumbersome fats calculation and saves more time for alignment design scheme comparison and selection. Secondly, the accuracy of three-dimension based calculation is higher than hats one, it applies true three-dimension differential theory to calculate cuts and fills amount of each differential triangle and its accuracy is controlled by designers. Thirdly, this algorithm is of high robust, it is suitable for calculating complex terrain like boundary between excavation and fitting, the old road reconstruction and interchange, the positions that are difficult to calculate for hats theory.
