BEARING CAPACITY CALCULATOR BY MEYERHOP AND BOYLES
(0/0)
Description
<ol>Meyerhof (1951, 1963): George G. Meyerhof developed a widely used method for calculating the bearing capacity of shallow foundations, considering the general shear failure case. His method incorporates factors such as the shape of the footing, the depth of the foundation, and the inclination of the load.
Bowles (1988): Joseph E. Bowles, in his book 'Foundation Analysis and Design,' extensively discusses bearing capacity theories, including those of Terzaghi, Meyerhof, and others. Bowles' work presents various methods for analyzing and designing foundations.
To calculate the bearing capacity, you can use the Meyerhof equation for the general shear failure case:
q_ult = (c * Nc * Sc * Dc * Ic) + (q * Nq * Sq * Dq * Iq) + (0.5 * gamma * B * N_gamma * S_gamma * D_gamma * I_gamma)
Where:
- q_ult = ultimate bearing capacity
- c = cohesion of the soil
- Nc, Nq, and N_gamma = bearing capacity factors (related to the angle of internal friction, phi)
- Sc, Sq, and S_gamma = shape factors
- Dc, Dq, and D_gamma = depth factors
- Ic, Iq, and I_gamma = inclination factors
- q = depth of the foundation (q = gamma * Df)
- gamma = unit weight of the soil
- B = width of the footing
Keep in mind that this is just one of the methods to determine bearing capacity. It's crucial to consider site-specific conditions, local practices, and soil investigation data when performing a bearing capacity analysis. It's always recommended to consult a geotechnical engineer or use specialized software to obtain accurate results for your particular project.
