Question

the negative skin friction on a pile develops when​

Answer 1

Answer:

Negative skin friction occurs when concrete piles are situated in soft soils, consolidating soil-mass, etc., resulting in a downward force that increases loading on shaft piles and reduces the bearing capacity of the piles.

Answer 2

Answer:

Negative Skin Friction

Explanation:

The negative skin friction is considered as the process when a skin friction will acts sinking downwards and surrounding due to the relative soil of the piles.

The movements of the drag will occur only when the segment of the pile will penetrate the soil that is compressed.

It will usually develop due to the construction process and also after the completion of any construction.

The negative skin fiction will depend upon time of construction that occurred and also due to soft soils consolidation.

• To assume the negative skin friction is as follows:

Where Ss.r(t) is settlement of soil which is reamining;

Ss(t) – soils that settle at the time t;

Ss.l – the limitation of the settlement of the subsoil foundation;

Sp(t) – piles settlement in the during of the time
