海氷盤を利用した冬期レクリエーションの安全性に関する研究

抄録

Nowadays people enjoy a variety of sports and recreations on frozen surfaces in winter. It is important to estimate the bearing capacity of an infinite ice sheet in order to ensure their safety. In this study, (1) we show in charts and graphs the estimated bearing capacity of ice sheets obtained by the deflection of ice sheets per unit load without breaking the ice; (2) we obtain an equation to calculate the bearing capacity of ice sheets with holes and indicate the results in charts; and (3) we describe in charts the critical traveling speed of loads moving on ice sheet when the bearing capacity is at minimum.
