}The foundation design of the API Std 650 self-anchored storage tanks should meet the requirements of foundation stability and deformation, that is, the API Std 650 self-anchored storage tanks foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API Std 650 self-anchored storage tanks and cause distortion and deformation of the tank wall and bottom plate.
