DISCUSSION

Settlement For the settlement, the effective over burden pressure, Po is calculated each layer has their own bearing capacity. Soil within the water table must minus 9.81Kn/ as the water value. Finding net consolidation pressure on contact area. Then it must be subtracted by excavation value We. Excavation value is calculated only on the size of footing, means not below the footing. Layer under it not counted. Then refer table 6-2 to find the influence coefficient. For the consolidation, the value of H, the thickness of clay layer that is considered. Settlement of secondary cannot be too much due to building will change its stiffness thus can collapse.
