【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.
[Abstract]:The ice condition detection method based on the physical characteristics of the tested medium is a new ice condition detection method, which was put forward by the research group of Taiyuan University of Technology in 2004. The basic principle of the method is introduced and compared with the traditional ice forecasting method. The paper introduces the new ice condition detection method in the field test of the ice and snow condition in the river reach of the Mohe River in Heilongjiang Province. The result of the test shows that, The ice condition detection method based on the physical characteristics difference of the measured medium can realize the continuous observation of the physical parameters of the ice layer (such as equivalent resistance, temperature gradient distribution, etc.). According to the data measured in 2015, it is the first time to put forward the "characteristic phenomenon of pre-opening river". Thus it can provide a feasible engineering detection method for the real-time monitoring of the ice state change during the period of the inland river freezing and the real-time prediction of the ice disaster before the Kaihe River.
