【摘要】：作为一种城市轨道交通工具,地铁以其用地省、运能大的特点在缓解城市交通压力方面起到了重要的作用,但是随着地铁的陆续开通和运营,许多城市都出现了运营后期隧道热环境恶化的问题。为了保证地铁的正常运行,地铁环控系统需要对隧道温度进行监测和调控,以确保最高温度不超出地铁设计规范的要求。然而,怎样实现对地铁隧道温度,尤其是对最高温度的合理监测是目前需要解决的问题。本文以屏蔽门制式地铁为研究对象,对隧道空气温度分布特性和隧道最高温度的分布位置进行了研究,从而为地铁环控系统隧道温度监测网络的建立和最高温度的监测提出建议。以屏蔽门地铁为研究对象,本文建立了典型的地铁隧道模型,并在该模型的基础上,利用SES计算机程序对地铁隧道内的热环境进行了模拟与计算。根据计算结果,总结得到屏蔽门系统地铁隧道内的空气温度分布基本特性和最高温度的分布位置。地铁隧道内的空气温度受多种因素的综合作用,本文通过改变这些因素,分别研究了轨道排热系统、列车相关因素、活塞风井配置形式与数量、区间隧道长度、室外气象条件和客流量对隧道空气温度分布的影响,探讨了各因素改变的情况下最高温度位置的变化规律,并由此提出对地铁隧道最高温度进行监测的方法。最后,本文模拟计算了成都地铁18号线初期、近期和远期夏季晚高峰上、下行线隧道内的空气温度分布情况,研究分析了隧道最高温度的数值及其分布位置,并据此建立了成都地铁18号线隧道温度监测系统方案。研究结果表明:屏蔽门系统地铁隧道内的温度以车站轨行区及其相邻的区间隧道为单位,呈现相似的分布规律;隧道最高温度的数值主要受列车发车密度、列车最高运行速度和轨道排热系统的影响;隧道最高温度出现在各站距出站端0～12m的轨行区,且主要受到列车停车位置和加、减速率的影响。在对隧道进行温度监测时,应在各站列车停车车头附近、距出站端0～12m的轨行区均布置监测点,以获取全线隧道最高温度值。针对成都地铁18号线的实际工程情况,本文建立了对应的隧道温度监测系统方案,并对最高温度监测点的布置和传感器的选择进行了阐述。
[Abstract]:As a kind of urban rail vehicle, the subway has played an important role in relieving the urban traffic pressure because of its land saving and large transportation capacity. However, with the opening and operation of the subway one after another, In many cities, the tunnel thermal environment deteriorated in the late stage of operation. In order to ensure the normal operation of the subway, the subway environmental control system needs to monitor and regulate the tunnel temperature to ensure that the maximum temperature does not exceed the requirements of the subway design code. However, how to realize the reasonable monitoring of subway tunnel temperature, especially the maximum temperature, is a problem that needs to be solved. In this paper, the characteristics of air temperature distribution and the location of the maximum temperature of the tunnel are studied by taking the shielded door subway as the research object. Therefore, some suggestions are put forward for the establishment of tunnel temperature monitoring network and the monitoring of maximum temperature in metro environmental control system. Taking the shield door subway as the research object, this paper establishes a typical subway tunnel model, and on the basis of this model, the thermal environment in the subway tunnel is simulated and calculated by using the SES computer program. Based on the calculation results, the basic characteristics of air temperature distribution and the distribution position of maximum temperature in metro tunnel with shield door system are summarized. The air temperature in the subway tunnel is affected by many factors. By changing these factors, this paper studies the rail exhaust system, train related factors, piston air well configuration and quantity, interval tunnel length, etc. The influence of outdoor meteorological conditions and passenger flow on the temperature distribution of tunnel air is discussed in this paper. The variation law of maximum temperature position under the change of various factors is discussed and the method of monitoring the maximum temperature of subway tunnel is put forward. Finally, this paper simulates and calculates the air temperature distribution in the downlink tunnel at the early, near and long term summer evening peak of Chengdu Metro Line 18, and studies and analyzes the maximum temperature value and its distribution position of the tunnel. Based on this, the temperature monitoring system of Chengdu Subway Line 18 is established. The results show that the temperature of the subway tunnel in the shield door system is similar to that of the subway tunnel in the railway station and its adjacent section. The maximum temperature of the tunnel is mainly affected by the train departure density, the maximum train speed and the track heat removal system. The maximum temperature of the tunnel appears in the rail line area of 0 ~ 12m from the exit end of each station, and is mainly affected by the train stop position and the rate of increase and subtraction. In order to obtain the maximum temperature value of the tunnel, monitoring points should be arranged in the rail line area of 0 ~ 12m away from the exit station near the front of the train stop at each station in order to obtain the maximum temperature of the tunnel in order to obtain the maximum temperature of the tunnel in order to monitor the temperature of the tunnel. In view of the actual engineering situation of Chengdu Metro Line 18, the corresponding tunnel temperature monitoring system scheme is established, and the layout of the highest temperature monitoring points and the selection of sensors are expounded.
