应用JTM-T400型温度计,测量宁波市轨道交通2号线一期工程地表下25m以浅的土壤温度,确定了各深度范围内的地温随气温的变化规律。通过气温与地下各深度范围内的地温的对比,清楚反映了地下各深度范围内的地温变化规律。为轨道交通提供设计参数。
Using the JTM-T400 thermometer, the soil temperature of 25m under the surface of the first phase of Metro Line 2 in Ningbo was measured to determine the variation law of ground temperature with temperature in each depth range. The comparison between the temperature and the ground temperature in the depths under the ground clearly shows the change law of the ground temperature in each depth. Design parameters for rail transit.
