Abstract

The inflatable dome (1) is used in the construction of part-spherical structures, and the side walls (1a) of the dome are tethered to a ground beam (2). The flexible base (1b) of the dome has an air tight double skinned wall (3, 4), each wall taking the shape of a spherical cap, and their circumferences. The space between the walls (5) is inflated to a pressure (P') which is higher than the pressure (P) within the dome. Consequently the space below the double wall (7) can be maintained at atmospheric pressure, with no tendency for the ground (8) to sink.
