Abstract: Reliability and security of hydraulic structures under winter conditions depend on the probability of ice formation and increase in ice thickness. Statistical investigations for inland waterways, lakes and reservoirs in the mountains of GDR enable the prognosis of ice formation as well as ice thickness, which can be the basis for the calculation of ice loads. Comparisons of GDR-standards for ice loads with international standards show that the Soviet standard SNIP 11-57-75 can be used for conditions of GDR, if the ice thickness is calculated in a way as referred to in this article. Recommendations for the prevention of ice load on steel-hydraulic structures are given. A new experimentation set for the investigation of ice formation on sub-zero cooled hydraulic structures is explained. The unsteady temperature fields in the trial bodies were compared with thermodynamic calculations.
