摘　　要：针对铁路沿线站点布局缺乏科学性及资源浪费的问题,提出一种基于测风站点间相似性度量的站点布局优化方案。利用京沪高铁江苏段铁路沿线附近90 km范围内的43个地面气象站瞬时风速数据,通过克里金插值,模拟得出铁路沿线以10 km为间距的31个测风站点风速数据。以模拟的31个站点作为现有地面测风站点,并根据测风站点地形将铁路沿线划分为多块区域,通过改进的相似度函数增减测风站点,将测风站点的等间距布站改良为非均匀布站,实现以最少站点数目准确监测各区域风速特征的目的。相比于以往区域布站方法,实现了对沿线的布局优化。通过对京沪高铁江苏路段进行实验发现,优化后确定的12个测风站点能够更精确地表征沿线风速特征。该方法对未来铁路沿线测风站网的建设具有参考价值。Aiming at the problems of lack of scientificity and waste of resources in the layout of stations along the railway,a station layout optimization scheme based on the similarity measurement between wind measurement stations is proposed.The program uses instantaneous wind speed data from 43 surface weather stations within a 90 km range along the Jiangsu section of the Beijing-Shanghai high-speed railway,and through Kriging interpolation,simulates the wind speed data of 31 wind measurement stations along the railway with a distance of 10 km.The 31 simulated stations are used as the existing ground wind measurement stations,multiple areas along the railway are divided according to the topography of the wind measurement stations,,and finally wind measurement stations are added or subtracted through the improved similarity function.The spacing station is improved to non-uniform station,achieving the goal of accurately monitoring of wind speed characteristics in each area with the least number of stations.Compared with the previous method of regional station deployment,the layout optimization along the line is realized for the first time.Through experiments on the Jiangsu section of the Beijing-Shanghai high-speed railway,the 12 wind measurement stations confirmed after optimization can more accurately characterize the wind speed characteristics along the line.This method can provide reference for the construction of the wind measurement station network along the railway in the future.
