Question

Please give the correct answer and do not copy answer from chegg because its wrong.Thank you.

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 %3D At 12m, eo = 0.55, Cc = 0.32, C; = 0.09, o'o = 300KN/m2 %3D 7m 5m Clay 3 10m Unit weight = 18KN/m %3D Friction angle = 0 degree 2 Cohesion = 100KN/m
