Abstract: In April 1999, the measurement and investigation work at the position of No. 3 pier of Songhua River highway bridge in Harbin was carried out. Built in the 80’s, this bridge suffers severely from ice floods. Before the ice cover melted, five ice pressure transducers were firmly installed at different locations at the head of No. 3 pier on the upstream side. During ice drift, using relative apparatus, measurements of ice pressure were performed. Through these measurements of ice pressure, two typical samples and two complete curves of ice pressure have been recorded by the measurement apparatus. Based on the records provided by the hydrologic observation branch during the period of this measurement, the water level of the drifting ice was classified as moderate. The magnitude of the drifting ice was not the largest observed. In fact, the drifting ice sheet that impacted on No. 3 pier was not the largest one either.
