摘要

Taking study on ice slush of Jinan section in Yellow river for example, the ice periods were tested and analyzed by geo-electricity testing. Two important conclusions were summarized as follows: Firstly, the high-frequency of electrical sounding curve was apparent quantitative relationship with the ice water flow. The relations between apparent resistivity and high-frequency section, the amount of ice in riverway were direct proportions. Hence, the quantity of the ice slush-flow in riverway could be reflected by differences of high-frequency and low-frequency curve. Secondly, whether there were ice-slush in river or not, the curvatures of high-frequency and low-frequency sections were similar to the same contour. The results studied here indicated that the decomposition of high-frequency and low-frequency curves by electrical sounding could be used as the recognition indexes of forecasting yellow river ice-slush.
