【摘要】：城际铁路由于列车高速度、高密度运行,一旦发生事故,后果严重。因此,对各种可能发生的灾害,如自然灾害(强风、暴雨、大雪、地震)和突发性灾害(异物侵入铁路限界),都要实施全面监测。为了解城际铁路的灾害监测体系,本文以佛肇城际铁路为例,以沿线自然环境调查研究结果为基础,结合佛肇城际铁路线路周边情况,提出佛肇城际灾害监测系统风、雨、异物侵限监测子系统传感器选型、监测布点选择、设备安装等方案。主要内容有:1、分析了佛肇城际铁路沿线风、雨等气象条件、地形条件,结合佛肇城际铁路工程特征,提出了佛肇城际铁路风、雨、异物侵限监测点设置方案。2、针对风监测子系统监测方案进行研究,经过安全和经济等多方面的比选,最终选择在佛肇城际沿线设置12处风监测点(每处设2个传感器),采用热场式风速风向仪,安装于接触网杆上,距离钢轨表面4米高。3、针对雨量监测子系统方案,经过安全和经济等多方面的比选,最终选择在佛肇城际沿线设置6处雨监测点(每处设1个传感器),采用压力感应式雨量计,安装于接触网杆上。4、针对异物侵限监测子系统方案,结合现场实际情况,最终选择在佛肇城际沿线设置12处异物侵限监测点,其中公铁并行且公路不低于铁路的地段11处,羚山隧道进口 1处,采用双电网传感器。
[Abstract]:Due to high speed and high density of trains, inter-city railway has serious consequences once accidents occur. Therefore, all kinds of possible disasters, such as natural disasters (strong wind, heavy rain, heavy snow, earthquake) and sudden disasters (foreign bodies intruding into railway boundary), should be monitored comprehensively. In order to understand the disaster monitoring system of the inter-city railway, this paper takes the Fozhao inter-city railway as an example, based on the investigation and research results of the natural environment along the line, combined with the surrounding situation of the Fozhao inter-city railway line, puts forward the Fozhao inter-city disaster monitoring system wind and rain. Foreign body invasion monitoring subsystem sensor selection, monitoring point selection, equipment installation and so on. The main contents are: 1. This paper analyzes the meteorological conditions, such as wind, rain, and other meteorological conditions along the Fozhao Intercity Railway, as well as the topographic conditions. Combined with the characteristics of the Fozhao Intercity Railway Project, it proposes the Fozhao Intercity Railway Wind and Rain. Set up the monitoring point of the foreign body invasion limit. 2. Study the monitoring scheme of the wind monitoring subsystem, through the comparison of safety and economy, etc., Finally, 12 wind monitoring points are set up along the line of Fozhao city (2 sensors are installed in each place, and the thermal-field wind speed and wind direction meter is installed on the catenary rod, which is 4 meters high. 3 meters from the rail surface.) aiming at the scheme of rainfall monitoring subsystem, After the safety and economic comparison, the final choice is to set up 6 rain monitoring points along the border of Fozhao city (one sensor at each place, using pressure inductive rain gauge). Installed on the catenary bar. 4, according to the scheme of foreign body invasion monitoring subsystem and the actual situation on the spot, 12 foreign body invasion monitoring points are finally set up along the border of Fozhao city. Among them, 11 places where the road is no less than the railway and the road is parallel, and the highway is not lower than the railway. Lingshan tunnel entrance 1, using dual grid sensor.
