I am dealing with expansive soils now.
If I only have testing results on natural moisture content, Atterberg Limits, and Clay fractions from disturbed soil samples collected from test pits, is there a way to figure out soil swelling pressure and amount of heave?
Any help will be appreciated.
I need to specify bitumen coating thickness on steel pipe piles and the surface preparation of the steel pipes in order to reduce downdrag. Anybody knows where I can get some references on these?
Thank you!
what are the differences for both structural design and geotechnical recommendations? Will they perform equally if differential settlement is a concern?
Structural engineers asked us to provide lateral loads on pile foundation allowing 0.5" head deflection for the following condition:
1. Pinned;
2. Fixed at the underside of a foundation;
3. Pinned 1 ft above grade;
4. Fixed 1 ft above grade.
I believe 1 is free head condition with applied...
To do a site investigation for a slab on grade, do we also investigate to 2 or 3 times width? If not, will the soft zones within 2 to 3 times width will become a concern?
Also, does anybody have experiences on constructing mini-storage facility on 4 to 5 m thick uncompacted fill? If it is...
If a 2m*2m square footing will be installed on a 5 m thick structural fill, how can I get the properties of the structural fill for the settlement and bearing capacity? Is there a reference having properties for different types of structural fills? If we do test in the laboratory or in the...
Based on sieve and hydrometer, the soil is classified as silt. But based on the LL and Plasticity Index, the soil is CI. Anybody has an idea where the inconsistency comes from.
