Calculation method of foundation settlement of vertical oil tank

With the continuous development of large-scale oil storage tanks, the foundation of oil tanks has also continued to grow. Among them, vertical oil tanks are storage tanks commonly used for storing crude oil, diesel, gasoline and other oil materials. This type of storage tank is set up as a cylindrical shape. The structure, the bottom of the tank is a circular flat bottom plate, and the load surface of the oil tank is basically horizontal, which can generally be regarded as a uniform load and has greater flexibility. The bottom plate of the vertical oil tank is in direct contact with the foundation soil. It is suitable for a flexible foundation, and its settlement characteristics are quite different from that of a rigid foundation.

For the settlement calculation of the foundation of a vertical oil tank, the one-way compression layered sum method can be used. The calculation method is to divide the foundation soil into several layers of compression within the calculation depth of the foundation settlement, and then find the sum. The calculation method of the compression amount of each layer is the same as the calculation method of the compression amount under the condition of no lateral deformation.
