A single vertical friction pile of diameter 500 mm and length 20 m is subjected to a vertical compressive load. The pile is embedded in a homogeneous sandy stratum where: angle of internal friction is = 30°, dry unit weight (yd)= 20 kN/m3 and angle of wall friction is 24/3. Considering the coefficient of lateral earth pressure (K) = 2.7 and the bearing capacity factor (Ng) = 25, the ultimate bearing capacity of the pile (in kN) is_

Explain the difference in manufacturing a cold rolled sheet pile and a hot rolled sheet pile. When is a driving template necessary? Name and describe two types of hammers used to install sheet pile. List 4 or the 6 methods used to install sheet pile in hard soil/driving conditions. Can a Driving Template have a second use, explain? What determines the size of a strut? When determining Web Yielding, explain what the distance “k” means.
