Abstract: When drifting ice in a river impacts on bridges and hydraulic structures, the magnitude of the ice force depends on the failure strength of the ice and the ice strength is a primary factor that determines the ice force that acts on the structures. The Songhua River, located in Northern China, is one of the rivers with the most serious problem with floating ice in the world. The ice strength in Harbin Reach of the Songhua River was determined. Using ice samples from this Reach, uniaxial, non-lateral-restraint compressive strength tests and flexural tests with simple beams loaded at three points, were twice carried out in 1998 and 1999.
