TASK 2 (LO2, 2.2) To further your development as an engineer, you are involved in a standard ground test procedure to determine ground quality for foundation design purposes. Your specific borehole test kit is listed below (fig1). Hammer mass = 63.5kg Pile dimensions External diameter = 50.8mm Internal diameter= 35mm Length= 650mm Mass= 5kg Drop distance 750mm. Fig 1 To set up the test procedure the hammer initially drives the pile 150mm into the ground. From this point, measurements are taken and each impact drives the pile a further 5mm into the ground. As part of the analysis calculate: 1. How much energy is lost when the hammer and pile impact. 2. The work done by the resistance of the ground. 3. The average resistance to ground penetration. Comment on your assessment regarding the relative density of the ground.
