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.

Question

**Problem Statement:**

Please round to the nearest Hundredth (i.e., 0.01). No Comma!

A square pile, 13 m long, is driven into a homogeneous sand layer. The pile's width (diameter) is 0.5 m. The standard penetration resistance near the vicinity of the pile is 17. Calculate the allowable bearing force (Qa) of the pile. Use FS = 2 and Briaud & Tucker method. Hint: Qa = Qu / FS

**Formula:**

Qa = \_\_\_\_\_\_ kN

*Note: The text mentions the width as diameter, which seems to be an error since it is a square pile.*
