摘　　要：基于被测介质物理特性差异的冰情检测方法是由太原理工大学冰情检测课题组于2004年提出的一种新的冰情检测方法,对方法的基本原理进行了介绍并与传统的冰情预测方法进行了比较.论文介绍了新的冰情检测方法在黑龙江漠河河道段冰雪情现场试验的情况,试验结果表明,基于被测介质物理特性差异的冰情检测方法可以实现对冰层内部物理参数(如等效电阻,温度梯度分布等)连续观测,根据2015年测得的数据首次提出"预开河特征现象",从而可以为内陆河道封冻期冰情变化实时监控、开河前冰凌灾害的实时预报提供一种可行的工程检测方法.Based on physical properties of measured medium difference method is by Taiyuan University of Technology, ice testing team in 2004, proposed a new ice detection method, in this paper, the basic principle of this method are introduced and compared with the traditional ice prediction method are compared. Paper introduces the new technique for detecting ice in Heilongjiang at Mohe river ice field test, the test results show that the ice detection based on physical properties of measured medium difference method can implement internal physi- cal parameters of ice （such as equivalent resistance, temperature gradient distribution, etc.）, continuous observation for inland river freeze ice changes in real-time monitoring, real-time prediction of ice disasters before talk detection method provides a feasible project.
