水电工程对外交通规划设计的传统方法繁琐复杂、成果直观性差、缺乏系统的理论模型。为此,以旭龙水电站为工程背景,结合地图Web API技术、WebGIS技术和最优路径算法设计了水电工程对外交通运输路径优化系统。首先针对该工程具有的多源、多路径以及多种运输方式特点的路径优化问题,建立了一种可自定义优化目标的多源多层路径优化模型,并采用最优路径算法求解求优;然后使用编程语言实现数学模型,并提出了基于百度地图API的数据自动获取和管理方法,以及结合WebGIS技术的方案可视化方法。应用结果表明:该系统可以实现从数据获取到方案优选全过程的自动化,以及基于GIS平台的方案可视化,验证了该系统的可行性与实际应用价值。

The traditional methods of external transportation planning and design of hydropower projects are cumbersome and complicated,poor visualization and lack of systematic theoretical models.In view of above challenge,based on the engineering background of Xulong Hydropower Project,this paper designs a route optimization system for external transportation of hydropower station by combining the map web API technology,WebGIS technology and optimal path algorithm.Firstly,aiming at the route optimization problems of multi-source,multi-path and multiple transport methods in Xulong Hydropower Project,we establish a multi-source and multi-layer path optimization model with user-defined optimization objectives,and use the optimal path algorithm to solve the model.Then a programming language is applied to realize the model,and an automatic acquisition method and data management mode based on Baidu map API is given,and a visualization scheme by combining the WebGIS technology is proposed.The application results show that the system can realize a whole automation process from data acquisition to scheme optimization,and the GIS-based scheme visualization.
