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.

The bucket is being supported be the three cables DA, DB andDC. Note that cables may only carry tension, or the forces are pointing awayfrom point D when analyzed.[1] If the tension in DA is 125 kN, calculate the components.[2] If the tension in DC is 135 kN, calculate the components.[3] If the tension in DB is 80 kN, calculate the components.
