A 30-m-long concrete pile is 305 mm x 305 mm in cross section and is fully embedded in a sand deposit. If nh = 9200 kN/m2, the moment at ground level, Mg = 0, the allowable displacement of pile head = 12 mm; Ep = 21 x 106 kN/m2; and FY (pile) = 21,000 kN/m2, calculate the allowable lateral load, Qg, at the ground level. Use the elastic solution method.

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.
