 note = {In snowy cold region, many concrete structures in rivers are degraded by combination of freezing and salt damage. In some cases, collision of river ice cause additional damages on concrete structures in river channel. We conducted field observation to clarify relation between river ice movement and acting force on concrete piles set on the bank of Abashiri River. Acting force can be evaluated with approach rate, plane area, length and thickness of river ice. We estimated river thickness with bottom tracking of ADCP in field tests and confirmed good relations between estimated value and actual value. We observed acting forces on sheet piles and calculated stress coefficients of ice to investigate evaluation methods.},
