METHOD AND APPARATUS FOR INCREASING THE VERTICAL LOAD BEARING CAPACITY OF ICE ABSTRACT OF THE DISCLOSURE In order to increase the vertical load bearing capacity of an ice field such as may be found in the Arctic, whereby buildings, drilling rigs, or the like may be supported, an inflatable hull is positioned beneath the ice, initially in deflated form. Inflation of the hull is carried out in conjunction with application of the load under control of level sensor means which govern the rate of inflation according to the deflection of the ice as the load is applied. Very high load bearing capacity may be obtained and maintained even for relatively thin ice, within a short period. Degree of inflation control apparatus may be employed to accomodate varying loads, and a multiple-hull system is contemplated for practicing the invention over relatively large areas.
