We have a project where H piles will be driven through a deposit of 7m thick calcerous sand. This material is found between 3 to 10m depth below the grade. I would like to know about the following:
1) Effect of driving through calcareous sands on skin friction. 2) Driving resistance. 3) Set up factor. 4) In the calculation of skin friction whether the k(lateral earth pressure) and f(coefficient of friction) values shall be reduced.
