Investigation and Application Progress of Mounded Steel Storage Vessels in China
Compared with above-ground storage tanks,the mounded storage tanks not only have better environmental protection and higher safety but also have the advantages of saving land resources and improving the plant working environment.However,the complexity of the soil-induced environmental loads also brings a series of new difficulties to the structural design of mounded storage vessels.The current application status was comprehensively analyzed including the mounded horizontal steel storage vessels and vertical vessels as well as spherical vessels in China.Some existing problems were discussed in detail,such as the lack of fundamental research,related criteria,application experience,and low investment income ratio.The future development trend was summarized for the mounded storage vessels in China.This work will provide some references for theoretical research,standard formulation,and engineering application of the mounded storage vessels.
