State and explain the failure of soil on the basis of Terzaghi’s analysis
On the basis of Terzaghi’s analysis the three types of shear failure occurs;
i. General shear failure: When footing is rested on dense sand or stiff clay, the settlement increases suddenly at particular loading is called as General shear failure.
ii. Local shear failure : When footing is rested on medium dense sand or clay of medium consistency, the gradual settlement increases at particular loading is called as
Local shear failure.
iii. Punching shear failure : When footing is rested on loose sand or soft clay, the settlement increases vertical diraction at particular loading is called as Punching shear failure.
