- Synopsis
- The world's first LNG underground tank with the largest capacity of 200 000 KL in the world is now under construction at Tokyo Gas new Ohgishima terminal.The roof of this tank is dome shaped structure made of reinforced concrete which supports the soil weight of about 40 000 ton laid on the roof and dead weight of 15 000 ton.In case of the doom roof to be flatter,the reasonable cost of underground tank is obtained.The experimental test of 1/20 scale model,the non-linear analysis and the design study used by codes were carried out for the purpose of confirming the safety of low-rise dome.In this paper,the R & D,the the design and the construction for the underground doom roof of RC are described.
