摘要
对广州地区有代表性土壤温度进行长期监测,获得不同地面状况、不同深度、不同月份土壤温度的月平均最高温度;通过数据分析,认为土壤温度受地表状况、季节和埋深的影响;综合考虑土壤温度的影响因素,给出广州地区电缆载流量计算用基准土壤温度推荐值。
Temperature of typical soil in Guangzhou is monitored for long to acquire mean monthly maximum soil temperature in different ground conditions,depths and months.Through data analysis,it is believed that the soil temperature is subject to ground conditions,seasons and burial depths.Recommended value of reference soil temperature used for cable ampacity calculation in Guangzhou is offered by synthetically considering factors influencing soil temperature.
