On-site verification trials using fly ash for reclamation behind bulkheads; Sekitanbai wo gogan uraumezai ni riyosuru genba jissho chosa

Abstract

As a method to utilize coal ash generated from coal burning power plants more effectively in bulk, its use has been studied as a reclamation material behind bulkhead structures in harbors and airports. Verification trials for the study results were performed at the Hekinan power plant of the Chubu Electric Power Company. The trials included the following: an experiment to verify horizontal soil pressure and active earth pressure when slurry made of fly ash added with cement and seawater was placed in frameworks installed behind bulkheads of a harbor, a slurry hardening test, environmental impact investigation, and constructibility investigation. As a result, a large number of findings were obtained, including the following matters: earth pressure of slurry which has been placed in a soil tank in about ten minutes would be measured as pressure of liquid, but it shifts to behavior as a soil in a relatively short time; the earth pressure after three hours agreed with static earth pressure calculated under provision of K{sub o} = 0.2; and a hardened body made with cement under a certain mixing ratio was obtained, which stands by itself at a height of 7.5 m at compression strength of 1.77 kgf/cm {sup 2}.  More>>
