轨交长期运营下所产生的土壤热堆积效应将会对地下区间产生严重的影响。为研究其温度变化规律,对上海轨交1号线某区间隧道断面的热环境进行了现场实测,分析列车运行因素对测试断面全天空气温度变化的影响规律。建议应对轨交区间环境进行持续监测,为今后研究热环境变化趋势建立数据储备,并尽快开展此类专题研究。
Under the long-term operation of rail transit, the soil thermal accumulation effect will have a serious impact on the underground section. In order to study the law of its temperature variation, the thermal environment of a certain section of tunnel in Shanghai Rail Transit Crossing Line 1 was measured on site, and the influence of train running factors on the air temperature change of the test section was analyzed. It is suggested that continuous monitoring should be conducted on the inter-sectioned rail transit environment to establish a data reserve for studying the trends of thermal environment changes in the future and to conduct such special studies as soon as possible.
