![]() ![]() Validity of the Bearing Capacity Equations (12.27) has to be modified according to the position of water level in the same way as explained in Section 12.7. (12.27) has not taken into account the effect of the water table position on the bearing capacity. ![]() Qu = vertical component of the inclined loadĬa = unit adhesion on the base of the footingĪf = effective contact area of the footing Qh = horizontal component of the inclined load In Table 12.3 The following terms are defined with regard to the inclination factors The tilt of the base and the foundations on slopes are not considered here. Equations for shape, depth and inclination factors are given in Table 12.3. Table 12.2 gives the values of the bearing capacity factors. However, the equations used by them for computing the values of Ny are different. All three investigators use the equations proposed by Prandtl (1921) for computing the values of Nc and Nq wherein the foundation base is assumed as smooth with the angle a = 45° + 0/2 (Fig. Vesic (1973, 1974) used the same form of equation suggested by Hansen. (12.27) two additional factors to take care of base tilt and foundations on slopes. Hansen (1970) extended the work of Meyerhof by including in Eq. ![]() The general form of equation suggested by Meyerhof for bearing capacity is Meyerhof (1963) presented a general bearing capacity equation which takes into account the shape and the inclination of load. (12.6) has been modified for other types of foundations such as square, circular and rectangular by introducing shape factors. (12.6) developed by Terzaghi is for a strip footing under general shear failure. ![]()
