The CPT Method of Determining Ultimate Bearing Capacity

Cohesionless Soils Relationship Between qc, Dr and 0 Relationships between the static cone penetration resistance qc and 0 have been developed by Robertson and Campanella (1983b), Fig. 9.15. The value of $ can therefore be determined with the known value of q . With the known value of 0, bearing capacity factors can be determined and  hence  Full Article…

Bearing capacity problem example 2

If the soil in Ex. 1 fails by local shear failure, determine the net safe bearing pressure. All the other data given in  Ex. 1 remain the same. Solution For local shear failure:

Terzaghi’s Bearing Capacity Theory

Terzaghi (1943) used the same form of equation as proposed by Prandtl (1921) and extended his theory to take into account the weight of soil and the effect of soil above the base of the foundation on the bearing capacity of soil. Terzaghi made the following assumptions for developing an equation for determining qu for a c-0 soil.  Full Article…

The Ultimate Bearing Capacity of Soil

Consider the simplest case of a shallow foundation subjected to a central vertical load. The footing is founded at a depth Df below the ground surface [Fig. 12.2(a)]. If the settlement, 5, of the footing is recorded against the applied load, Q, load-settlement curves, similar in shape to a stress-strain curve, may be obtained as  Full Article…

Shallow foundation ultimate bearing capacity

It is the customary practice to regard a foundation as shallow if the depth of the foundation is less than or equal to the width of the foundation. The different types of footings that we normally come across are given in Fig. 12.1. A foundation is an integral part of a structure. The stability of  Full Article…
