Haul road routing method for rockfill dams with interval-discretized elevation adjustment
摘要
Abstract
This paper constructs an optimization model for selecting on-site haul roads during rockfill dam construction based on a strategy of interval-discretized elevation adjustment,to address the issue of suboptimal haul road routing,which is frequently exacerbated by steep terrain and slope constraints.This model,rooted in the theoretical framework of Least-Cost Path Analysis(LCPA),incorporates critical factors-such as path length,elevation modification,and turning constraints-while leveraging the Dijkstra's algorithm for its efficient calculations of a solution.A comparative case study reveals that in comparison to conventional methods,it reduces the haul road length by 17.33%and the overall cost by 16.17%,improving significantly the cost-effectiveness and rationality of the routing scheme,and thereby validating its performance.And its applicability is further exemplified through a case study of the Cihaxia high concrete-face rockfill dam on the upper Yellow River mainstream.The method obtains a route of construction that agrees closely with the engineer-designed path that was refined using multiple iterations,and thus it would be an innovative solution to the planning of haul road in complex terrains.关键词
