In the absence of a strong layer at a reasonable depth, the building can only be built on a floating foundation which reduces the shear stresses to an acceptable value. Type 2: The shear strength of the foundation soil is so low that rupture of the soil would occur if the building were to be founded at ground level. A floating foundation is used to reduce settlements to an acceptable value. Type 1: The foundation soils are of such a strength that shear failure of soil will not occur under the building load but the settlements and particularly differential settlements, will be too large and will constitute failure of the structure. While dealing with floating foundations, we have to consider the following two types of soils.

The foundations of this type are sometimes called partly compensated foundations (as against fully compensated or fully floating foundations). The excavation stage of the building is the critical stage.Ĭases may arise where we cannot have a fully floating foundation. 14.4(c) without passing through stage 14.4(b). However, it may be noted, that we cannot jump from the stage shown in Fig. The result is zero settlement of the building.

This is the principle of a floating foundation, an exact balance of weight removed against weight imposed. 14.4(c) without the intermediate case of 14.4(b), the building in Fig. Since settlements are caused by an increase in effective vertical pressure, if we could move from Fig.

Since the water level has not changed, the neutral pressure and the effective pressure are therefore unchanged. If the weight of the building is equal to the weight of the soil and water removed from the excavation, then it is evident that the total vertical pressure in the soil below depth D in Fig. 14.4(c) shows a structure built in the excavation and completely filling it. 14.4(b) shows an excavation made in the ground to a depth D where D > d w, and Fig. 14.4(a) shows a horizontal ground surface with a horizontal water table at a depth d w below the ground surface. This principle of flotation may be explained with reference to Fig.
#MAT FLOATING FOUNDATION FULL#
A floating foundation for a building is defined as a foundation in which the weight of the building is approximately equal to the full weight including water of the soil removed from the site of the building.
