摘要
针对地质灾害危害输电线路安全的问题,提出了计及地质灾害风险的输电线路路径选择模型。首先将影响因素划分为成本和地质灾害影响因素,成本影响因素采用熵权法与模糊层次分析法组合赋权,地质灾害因素采用德尔菲法赋权,然后进行空间叠置分析,建立计及地质灾害风险的输电线路空间建模路径选择模型,采用Dijkstra算法实现模型求解。最后以某地区作为实验区进行仿真分析,得到线路成本较未考虑地质灾害风险之前降低20.57%,且线路长度缩短274.5米,并有效避开了地质灾害频发区域。
Aiming at the problem that geological disasters endanger the safety of transmission lines,a model of transmission line selection that takes into account the risks of geological disasters is proposed.Firstly,the influencing factors are divided into cost and geological hazard influencing factors.The cost influencing factors are weighted by the combination of entropy weight method and fuzzy analytic hierarchy process,and the geological hazard factors are weighted by the Delphi method.Then the spatial overlay analysis is carried out to establish the route selection model of transmission line spatial modeling with consideratin of geology disaster risk,which is solved by Dijkstra algorithm.Finally,simulation analysis is conducted in certain experimental area,it is found that the line cost is reduced by 20.57%and the line length is shortened by 274.5 meters,effectively avoiding the areas with frequent geological disasters.
