Long-Term Deep-Ocean Test of Concrete Spherical Structures. Part I: Fabrication, Emplacement, and Initial Inspections
The report summarizes the fabrication, emplacement and inspections during the first 1.2 years of submergence of eighteen 66-inch-OD concrete spheres. The spheres are located 4 miles south of Santa Cruz Island, California, in depths of water from 1,840 to 5,075 feet. The purpose of the test is to collect data on time-dependent failure, permeability and durability of concrete pressure-resistant structures. Findings from the inspections showed that two spheres located at the depths of 3,725 and 4,330 feet had imploded and that the quantity of seawater which permeated through the concrete for phenolic-coated spheres was about 0.8 cu ft and for uncoated spheres it was about 1.6 cu ft. This test program is planned to continue through 1981 (total of 10 years). (Author)
