A Achievement in Constructing Shell of Flat Round of Reinforced Concrete with “Sppat of Gas”of Metallic Oil Tank on the Tibetan Plateau

To fill in pressed air into the stand steel oil tank also to use shell of steel tanker as a model for eonstruct shell of reinforced concrete was proved by the the construction of six 5000m³ on the Tibetan Plateau.Eevn under the less favourable condition.It is an effective simple way.It has remarkable pra- etical use and economic benefit.In the article the reliability use analyzed and the result was certain.It can be widely used.
