Bearing capacity, slope stability, safe slope hiegth
Bearing capacity, slope stability, safe slope hiegth
(OP)
Please would someone help me how to estimate the bearing capacity of a foundation soil for waste dump design. It is not pure clay, but rather c and phi soil material.
I need your help
Thank you.

The rational method for calculating "bearing pressure" is fundamentally a rotational shear failure mode. It's essentially a slope stability function, but the driving force is from a load applied on the surface. If you can show that "bearing soils" below the sloping waste can support the fill slope and maintain a safety factor of X.0 to x.5 or such, you have essentially "solved" the bearing capacity problem. Bear in mind (no pun intended) that this bearing capacity "solution" will have no relation to building foundations and that's a good thing. If you need to address bearing pressures for building foundations, you'd need to resize the problem and use the foundation width, stress bulb and things of this nature (well address settlement too).
I remain baffled that the need to solve for "bearing capacity" below landfills remains in the regulations so many years later. . .

Why are some people not considering the issue as impact of a vertical load on underlying material which have limit to the load it can carry. What is your view.

Not sure what this means. A slope stability assessment of the waste and its interaction with the "foundation soil" (i.e., deep-seated rotational failure or wedge type failure depending on the geology) is exactly what you describe. If you consider the macro scale a waste pile mobilizes stresses to great depths and can induce shear failure (depending on soil strength) along a number of failure planes. This "impact of a vertical load on underlying material" needs to be evaluated. However, if you think about it, it's not the vertical loading that's really being evaluated, but the shearing forces that lead to the rotational failure. If you just want to evaluate the impact of vertical loading do a settlement calculation and move on. . .

Thank you. Do you have some materials to that effect ?
