👉ስለ Bearing Capacity ከትላንት የቀጠለ
.
▶Modes of failure (Part two)
.
1. GENERAL SHEAR FAILURE
*General shear failure involves total rupture of the underlying soil. There is a continuous shear failure of the soil from below the footing to the ground surface.
*The value of Quilt divided by the width B and length L of the footing is considered to be the ultimate bearing capacity (qult) of the footing.
A general shear failure occurs for soils that are
in a dense or hard state.
.
2. LOCAL SHEAR FAILURE
Local shear failure involves rupture of the soil
only immediately below the footing.
*There is soil bulging on both sides of the footing, but the bulging is not as significant as in general shear.
*Local shear failure can be considered as a transitional phase between general shear and punching shear
* A local shear failure occurs for soils that are in
a medium dense or firm state.
.
3. PUNCHING SHEAR FAILURE
*Punching shear, the soil outside the loaded area
remains relatively uninvolved and there is minimal movement of soil on both sides of the footing.
*The process of deformation of the footing
involves compression of soil directly below the
footing as well as the vertical shearing of soil
around the footing perimeter.
*A punching shear failure occurs for soils that
are in a loose or soft state.

👉Bearing Capacity
.
▶ለ ዛሬ Part One እናቀርብላችኋለን 👇
.
♧ Bearing capacity is the capacity of soil to
support the loads applied to the ground.
♧ The bearing capacity of soil is the maximum
average contact pressure between the foundation
and the soil which should not produce shear failure
in the soil.
♧ Ultimate bearing capacity is the theoretical
maximum pressure which can be supported without
failure;
♧ Allowable bearing capacity is the ultimate
bearing capacity divided by a factor of safety .
♧ There are three modes of failure that limit
bearing capacity:
□ General shear failure,
□ Local shear failure
□ Punching shear failure.
