Abstract
Ice sheets in rivers, lakes, lagoons, port in cold regions are used for a variety of purposes. They are used as tracks on the ice, as roads for automobiles, as runways for airplanes, and as footholds for the construction of structures. Knowledge of physical and dynamic characteristics of natural ice sheets and techniques to estimate the hearing capacity of natural ice sheets against vertical loads are required to safety in using ice sheets. In this study, the authors indicate the theoretical values of the bearing capacity and the deflection of ice sheets under the condition of partial flooding, and compare with the experiments values, and made the experiments with the longtime-loads.
