a. Exploration boreholes on site show a horizontal water table at a depth of 4.5 metres. The borelog information is given in Table 2 (QB2). Calculate the total, effective and pore water pressure values at the base of each layer in kN/m2. (Take the unit weight of water as 9.81KN/m3). Please used the customised bulk density values in your calculation. The customised bulk density should be calculated in the following way: 1) Take last two digital numbers from your student ID 2) Sum them up and divide by 100 3) Then add the number on the given bulk density values. For example, ID: 1234567, (6+7)/100=D0.13, then the customised values in the calculation should be 1.6+0.13=1.73; 2.0+0.13=2.13; 1.7+0.13=1.83; 1.5+0.13=1.63; 1.9+0.13=2.03.
