利用探地雷达探测黄河弯道及桥墩周围冰层厚度
Measuring ice thickness around the curve and piers in the Yellow River with ground penetrating radar
摘要
Abstract
The freezing process of yellow river is a key point in the study of Yellow River ice flood prevention ,detection of the ice thickness around the curve and piers has important significance for prevention of the ice flood .The ground penetrating radar has the advantages of portable ,highly efficient ,continuous ,fast and real time for ice thickness detection .The frequency of the radar antenna determines the penetration depth and resolution of the radar wave .From the radar images ,the air‐water interface and ice‐water interface could be clearly identified .The accuracy of the measurement results was further improved by using ice thick‐ness data from the field drilling to calculate radar propagation velocity in the ice .The measurement results clearly showed that the distribution of ice thickness at the bend and pier was uneven .The ice on the north side of piers and the main channel of the curve was thicker .The ground penetrating radar with 200 Mhz antenna could penetrate the Yellow River ice ,and the radar ima‐ges could clearly show the ice‐water interface .This study could provide the basic data for the analysis of the yellow river ice freezing and melting process and governance of the ice jam in break‐up period .关键词
