| Abstract: | This paper presents a new method for the optimization of alignments in rail- way design. A recurrence relation model is developed to represent the railway line in space. Along the manual initial horizontal alignment, using the combination of generalized reduced gradient and gradient projection techniques by means of DTM and computer, the optimization of both vertical and horizontal alignments can be realized. Several examples are worked out with satisfactory results, sho- wing the feasibility of the method. |
