Concept explainers

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.

A retaining wall has failed as shown in the diagram below. A block of soil (shown in yellow) is
analyzed in the field. Your careful field examination shows that the failure surface is at an angle
of approximately 45 degrees with the horizontal.
Your calculations (which have been checked for accuracy) show the following values for the
stresses on the yellow block:
Horizontal Plane:
Vertical Plane:
Normal Stress = 19 kN/m²
Shear Stress 14 kN/m²
Retaining
wall
Normal Stress = 36 kN/m²
Shear Stress = -14 kN/m²
Now you must find:
(1) The maximum and minimum principal stresses and
(2) The normal and shear stress on the failure plane.
Using the pole method and verify your results using equations.
