Soil shear failure

Web01. Resting Foundations on Poor Soil or at Inadequate Depth: The foundation may fail due to failure in shear i.e. due to excess load, due to sliding or due to overloading. Hence they need to be placed at a minimum depth. Foundations resting on poor soil or at low depth results in the movement of the building as the soil settles eventually. WebThe failure is accompanied by the appearance of failure surfaces and by considerable bulging of a sheared mass of sand as shown in Fig. 12.4(a). This type of failure is designated as general shear failure by Terzaghi (1943). Foundations on sand of relative density lying between 35 and 70 percent do not show a sudden failure.
