    Calculation For Bearing Capacity As Per IS: 6403: (Soils With Cohesion and Shearing Resistance)

    Uploaded by

    radhikas49
    The document provides the calculation for bearing capacity of soils with cohesion and shearing resistance according to IS: 6403. It breaks the ultimate bearing capacity (Qult) into three parts: cohesion term (X), effective overburden pressure term (Y), and submerged weight term (Z). It then lists the soil properties, relevant dimensions, and factors used to calculate X, Y, and Z. The calculations determine X = 27.6 T/m^2, Y = 0.00 T/m^2, and Z = 0.00 T/m^2, giving a total ultimate bearing capacity of Qult = 27.6 T/m^2. The design bearing capacity is calculated as
