摘　　要：通过对冰情检测现场环境涉及的被测介质冰、水在室温至-30℃温度范围内等效电阻与温度值的取值规律进行研究,利用冰与水等效电阻与温度值存在较大差异的特点,设计了冰情检测传感器,并在黄河万家寨水库进行了现场冰情连续观测试验,对采集数据的分析表明,新的冰情检测方法和设备可以准确实现对水库冰情厚度变化过程的实时全程监测。The variation in the equivalent resistance and temperature volues of measured medium ice and water,which were involved in the detection field emvirenment of ice conditions,was investigated in the temperature range of room temperature to-30℃.Furthermore,the characteristics of the large difference in the equivalent resistance and temperature between ice and water was used to design the dotection sensor of ice conditions.On-site continuous observation test was conducted on ice conditions in wanjiazhai reservoir.The analysis of the collected data shows that the novel method and equipment for ice condition detection could accurately achieve real-time and all-process monitoring of ice thickness in reservoir.
