摘　　要： 以黄河济南段冰凌研究为例,采用电测深方法对黄河凌汛期典型断面进行了地电测试,并与无冰情况下的测深曲线进行了对比,结果表明,有冰时视电阻率高于无冰的情况,随着河道流冰量增加,视电阻率增大,有冰和无冰测深曲线间的面积与河道流凌量成正比关系,采用地电测试技术模拟河道断面流凌量是可行的。 It conducts terrestrial electricity tests for the typical cross-section in ice-run period of the Yellow River by using electric sounding method and taking the study on ice-run in Jinan Section of the Yellow River as an example and compares with sounding curve under the condition of no ice.The outcomes show that the apparent resistivity with ice is higher than that without ice,apparent resistivity increases along with the increase of ice-run in the channel,the area of sounding curve of with and without ice and the ice-run volume of channel is in direct proportion relations and using the techniques of terrestrial electricity test to simulate the ice-run of river section is feasible.
