engineering recuitment MP Vyapam Sub Engineer Mock Test 2024 Soil Mechanics and Foundation Engineering Earth Pressure
The critical vertical depth Hc of free standing soil can be upto active earth pressure, is given by _______
Where ‘c’ is cohesion, ‘γ’ is the density of the soil, ‘h’ is the depth of filling and ‘ϕ’ is the angle of internal friction.1
\({{\rm{H}}_{\rm{c}}}{\rm{\;}} = {\rm{\;}}\frac{{{\rm{\gamma h}}}}{2}{\tan ^2}\left( {45 - \frac{\phi }{2}} \right)\)
2
\({{\rm{H}}_{\rm{c}}}{\rm{\;}} = {\rm{\;}}\frac{{{\rm{\gamma }}{{\rm{h}}^2}}}{2}{\tan ^2}\left( {45 - \phi } \right)\)
3
\({{\rm{H}}_{\rm{c}}}{\rm{\;}} = {\rm{\;}}\frac{{4{\rm{c}}}}{{{\rm{\gamma }}\tan \left( {45 - \frac{\phi }{2}} \right)}}\)
4
\({{\rm{H}}_{\rm{c}}}{\rm{\;}} = {\rm{\;}}\frac{{4{\rm{c}}}}{{{\rm{\gamma }}\tan \left( {45 + \frac{\phi }{2}} \right)}}\)
