A large number of storage tank accident analyses at home and abroad show that the uneven settlement is the main reason for the storage tank accidents. Uneven settling of the tank can affect the proper operation of the tank. The deformation of the tank walls in different degrees is also caused by uneven settlement, and the deformation of the tank walls in different degrees is gradually increased along with the time, so that the oil tank has a leakage problem, and the storage tank cannot normally complete the preset function, namely the storage tank is scrapped; secondly, large-scale settlement of the surrounding foundations of the storage tank can cause the tank wall of the fixed top to be torn, directly causing crude oil leakage, which can create a significant potential hazard to the storage tank safety.
The safety problem of the large-scale oil storage tank as an important storage device in the petrochemical industry is not negligible. At present, the research method of the storage tank settlement mainly takes theoretical derivation and finite element numerical simulation as main points. The finite element method has many disadvantages: the theoretical model of the storage tank sedimentation is established by simplifying the load, boundary conditions and structure of the storage tank to a certain extent under different conditions, is over-ideal and has greater limitation; in the finite element simulation, if the influence of factors such as a perforated connecting pipe and the like is neglected, the whole geometric structure and the borne load of the large-scale storage tank can be regarded as the axial symmetry problem, so that the simulation result is greatly different from the actual simulation result. Meanwhile, the sedimentation of the storage tank has certain influence on the effects of various nondestructive detection means, so that the design of the storage tank sedimentation simulation device for simulating various working conditions of the storage tank and verifying various detection methods is very necessary.
