Hi, I need to define a return period for the probable maximum flood (PMF). From the hidrology i have the return period vs volume from 5 to 10.000 years. I also have the PMF volume. What would you recommend? Fitting a curve with log or other type? Is there any literature that talks discusses PMF...

What information can you get from the test without in situ density data?

Hi, Anyone has experience using EDG in sandy soils? Besides safety matters, any advantage over a nuclear one? Thanks

Hi, thanks for your replies. Seismic refraction results: 30 m of sand with Vp < 450 m/s. What kind of pile approach would you suggest?

Hello, I want to hear your thought of doing a cut in a sand dune of 100 m height with natural slope of 2H:1V. We need to cut for a road about 8 m, and then use a 2V:1H slope. The soil is a SP-SM sand dune, very loose. What kind of stabilization system (ie. soil nailings) would you recommend...

Hi, Im reataching the spreadsheet, first with phi' and cohesion results (effective). Please let me know if you think they are ok. Thanks.http://files.engineering.com/getfile.aspx?folder=1e905bfe-6cb4-4357-a1a2-497e932d1767&file=Triaxial_CIU.xlsx

Thanks for your answer. I think the material is from volcanic ash (alofanic) and thats why the remould resistance is bigger than the indisturbed. The in situ density test gave this results: Wet density 1,65 t/m3 w% 48,20 Dry density 1,11 t/m3. The structure is a house with no big loads. What...

Hi all, thanks for your help. L0k, im considering a 1x1 m square foundation. The unconfined compresion test of a not perturbated sample has this results: -Undrained shear strength, Su: 0,32 kgf/cm2 -Undrained shear strength of remolded sample, Su: 0,89 kgf/cm2 Consolidation test (see...

THanks a lot for the help. Im reattaching the spreadsheet with some results. Please let me know what you think. Thanks.http://files.engineering.com/getfile.aspx?folder=2bb73d1b-b708-4ab4-95d6-e49151ba3bdd&file=TX_CIU_V2_TEST.xlsx

Hello there, i was wondering if someone could help me interpreting this triaxial undrained test. I need to obtain the undrained shear strength (Su) in terms of the effective vertical pressure: Su/Sigma'v. Also cohesion and friction angle. Im attaching the spreadsheet with the results. Thanks...

Hi guys, what would you suggest to use for determing bearing capacity of shallow foundations on a high plasticity silt? The in situ permeability test were about 1E-04 cm/s. Water table is about 4 meters deep. Would you use drained or undrained analysis? The results from the undrained triaxial...

Hi, What are the advantanges of mohr coulomb over UBCHYST? Thanks.

Hi, i need to calculate primary consolidation settlement for a 100 meters NC clay (GS=2,71 Ysat =1,75 ton/m3), with no soil above, and a very granular soil beneath the clay strata. The surcharge is 0,25 kg/cm2. I also need to calculate the time for 50% and 90% of consolidation. Im attaching...
