Geotechnical Engineering Basic Interview Questions MCQ quiz Click here for Geotech Quiz 1.What are the basic principles of foundation design? 1. The foundation must be stable against shear failure of the supporting soil. 2. The foundation must not settle beyond a tolerable limit to avoid damage to the structure. 2.How do you determine the bearing capacity of soil? The ultimate bearing capacity , or the allowable soil pressure, can be calculated either from bearing capacity theories or from some of the in situ tests. The most popular bearing capacity calculation methods are 1. Terzaghi's bearing capacity theory 2. The general bearing capacity equations 3. Field tests According to Terzaghi's bearing capacity theory the soil's ultimate bearing capacity is dependent on density , cohesion, angle of friction of soil, shape, breadth and depth of footing. It also depends on the depth of...
