The client cannot remove the frost susceptible soils and considering a compressible expanded polystyrene fill forms, so they need the estimated amount of frost heave.
Hello everyone,
I am looking for a way to estimate frost heave of soils without specialized laboratory testing or investigation. I have frost depth, hydrometer results (showing 54% silts), and moisture content.
Is there a straightforward way to obtain a reasonably acceptable estimate with a...
Hi everyone,
I have a geotechnical report that provided an Ultimate Limit State (ULS) bearing capacity of 2000 kPa for silty sand soils with N-values greater than 50 (reaching about 70 blows per 0.3 m). My question is: Is there an upper limit to the ULS value where a geotech would not consider...
Thank everyone, and sorry for wasting your time on this. I am not really a Geotechnical engineer, but work with few and I am trying to understand how things work in the geotech world. I agree with CarlB, I believe there is a typo in this equation, but I don't access to the CFEM to confirm, as I...
Hey everyone,
In the CFEM, there is an equation by Burland and Burbidge (1985) for foundations on normally consolidated coarse-grained soils:
\[ S = B^{0.75} \times \frac{1.6}{N_{60}^{1.4} \times q} \]
I believe that this equation is based on observed data, but there are a couple of things I'm...
Could someone please explain how to evaluate bearing capacity using ULS? (I'm in Canada, if that makes a difference.) I have tried finding answers and reading reports, but I never clearly understand how ULS and SLS are calculated.
1) Is ULS a factored ultimate bearing capacity? If so, why do...
