In order to solve the problems of strong technicality,high risk and difficult construction in the current bottom renovation of vertical steel oil storage tanks,this paper,combining with the exploration and practice of bottom renovation in storage tanks within recent three years,introduces four bottom renovation methods,namely the jacking method,the compound method,the central plate removing method,and the edge board demolition and change method. On the basis of determining relative standards for bottom renovation, this paper expatiates on the operation procedure. The research has a very important guiding role in unifying technical standards of tank bottom renovation,organizing scientific construction,insuring construction safety,and improving quality and efficiency.
