怀化高速洪江服务区雷电灾害的防护

为降低山区高速公路雷电灾害的风险，以怀化高速洪江服务区为试点，选取周边2007-2016年的闪电数据，结合区内环境和天气系统，采用数理统计方法分析服务区的雷电特征、雷电风险等级等.洪江服务区属多雷或强雷地带，雷电风险逐年递增，雷电的密度呈东多西少、强度呈西强东弱的趋势，特别是偏东和东北方位约200 m（服务区加油站附近）以远是大片的高雷区.西风带与东风波天气系统会对服务区雷电产生不同的影响.建议考虑服务区环境和雷电风险等级，按标准对防雷设施进行检测整改，加强偏东和东北方位的防雷设施建设，开展雷电灾害防护宣传等以减少雷电灾害的发生.

Lightning and Meteorological Disaster Prevention in Hongjiang Highway Service Area of Huaihua

In order to reduce the risk of lightning disaster in mountainous areas,the Hongjiang expressway service area in Huaihua was selected as the pilot and the center of the square.By selecting the 60 km square range of lightning data from 2007 to 2016,combined with the surrounding environment and weather system,using mathematical statistics to analysis the lightning characteristics of the service area,lightning risk level and so on.Hongjiang expressway service area is lightning prone area or strong area,lightning risk increased year by year,the density of east lightning was much more than the west,the intensity of west was stronger than east,especially the east and northeast of about 200 m (service area near the gas station) away is a large area of lightning high risk area.Westerlies and easterly wave system have different effects on the lightning of service area.It is recommended to consider the service area environment and lightning risk level,check and rectify the lightning protection facilities according to standard,strengthen the construction of lightning protection facilities in the east and northeast of the country,and carry out lightning protection and publicity to reduce the occurrence of lightning disaster.
