A soil profile is provided below. The estimated stresses from a spread footing overlying a 9 meter thick normally consolidated clay layer are: 180.0 kN/sq m (top of the clay layer) 97.2 kN/sq m (middle of the clay layer) 64.3 kN/sq m (bottom of the clay layer) Estimate the primary settlement (in meters) of the clay layer assuming Cc'= Cc/log(1+eo)= 0.22 and Cs'=Cs/log(1+eo) = 0.04 taken from consolidation curves. ASsume the pre-consolidation pressure is 100 kN/sq m. Assume no settlement from the overlying sand layer.

Braced cuts

The braced cut is a method of providing lateral support to the soil in foundation trenches, to prevent the trenches from deformation by the caving in of soil and resisting it from moving laterally. During shallow excavation in firm soil, generally, slopes are provided to resist the caving in of soil. During shallow excavation in soft soil and deep excavation, the chances of caving in of soil increase. Hence, it becomes necessary to make a provision to resist the deformation of trenches due to caving in of soil. The braced cut is the method used for such conditions. The excavation using braced cuts is a bit uneconomical as compared to the traditional open-cut excavation method but provides better safety than the cut excavation method.
