Definition of ultimate settlement of foundation

In the foundation medium, under the load of the superstructure, the amount of decrease in the surface of the foundation when it reaches stable compression is called the final settlement of the foundation.

So how is the final settlement of the foundation calculated?

The calculation of the settlement amount needs to be divided into several cases for calculation

First, calculation for the case of one-dimensional compression of a single soil layer

Second, the layered sum method for the final settlement of the foundation

Calculation principle of this method

1.Assuming a linear distribution of base pressure

2. Additional force is calculated by elastic theory

3. Only one-way settlement occurs

4. Calculate only fixed settlement

The calculation of the ground settlement is of great significance to the determination of the method of foundation reinforcement and its construction, so the calculation of the ground settlement is a very important link, and each calculation formula needs to be treated carefully.
