![Check the total settlement of a group of pile as shown in Figure 1. The total allowable settlement is
set not exceed 3% of the pile diameter and the overconsolidated ratio (OCR) of the clay is more than
1. The groundwater table is located 15m beneath the ground level. The diameter of the pile, b is
0.5m and the spacing between piles, s is 2m.The pile group is subjected to foundation load of
5425kN. The laboratory testing data for the soil samples taken are as follows:
At 5m, eo = 0.55, Cc = 0.32, C; = 0.09, o'o = 150kN/m?
At 10m, eo = 0.55, Cc = 0.32, Cs = 0.09, o'o = 225kN/m2
