Zusammenfassung:The invention provides a sealing load verification method and device for a storage tank manhole sealing element, equipment and a medium. The sealing load verification method for the manhole sealing element of the rocket storage tank comprises the following steps: constructing a load structure model of the manhole sealing element according to size information, attribute information and linear pressure information; in a bolt pre-tightening state, determining a first residual strength coefficient of a single bolt in the load structure model based on the attribute information and the first bolt pressing force; in a bolt operation state, determining a second residual strength coefficient of a single bolt in the load structure model based on the attribute information and the second bolt pressing force; and comparing the first residual strength coefficient with the second residual strength coefficient according to corresponding standard coefficients, and obtaining a first sealing load verification result of the manh
