The earth pressure distribution due to surcharge load q per unit area ...
The earth pressure distribution due to surcharge load q per unit area is rectangular.
Explanation:
When a surcharge load is applied on the soil surface, it results in an increase in lateral pressure exerted on the soil mass. The distribution of this pressure is not uniform and depends on various factors such as the type of soil, the depth of the surcharge load, and the angle of the surcharge load.
The earth pressure distribution due to surcharge load q per unit area is rectangular. This means that the lateral pressure exerted on the soil mass is constant and uniform over a certain depth range. The rectangular pressure distribution is assumed to be valid for shallow surcharge loads, which are less than or equal to the width of the foundation.
The rectangular distribution of earth pressure due to surcharge load is based on the following assumptions:
1. The soil is homogeneous and isotropic.
2. The surcharge load is applied uniformly over the soil surface.
3. The surcharge load does not change the vertical stress distribution in the soil.
4. The lateral pressure distribution is independent of the depth.
In conclusion, the earth pressure distribution due to surcharge load q per unit area is rectangular, and it is assumed to be valid for shallow surcharge loads.
