Hi dears,
I had a discussion with an geotechnical expert on the parameters should we comsider for slope stability based on FHWA report NO.017
in this report it says we should consider global FOS=1.5 and also we should (as i understand) use FOS=1.8 for reinforcement and FOS=2 for bond strength...
Hi everyone,
We are going to stabilize an excavation using anchored wall, at depth 10m we faced collapsible soil which I think it should be loose GP withoud any cohesion, our hole length is 17m and when we drill with 10 degree slope at length 6-7 m hole collapses and it is imposible to go...
Hi there,
I have a small question on soil nail test, plz help. (I would be more grateful if PEinc also comments)
for proof test FHWA says that we should calculate LBPt as greater of 3 m and 0.9*A*fy/Qall*FSproof then DTL=LBPt*Qall
for verification test is the same except FS=2.5-3 instead of...
Dears,
We are going to design an anchored wall up to 36 m excavation, the soil has the following conditions:
0-10m depth clayey sand
more than 10m sandy clay
there is no water table observed.
from the top to bottom SPT-N>50 blows/30cm
direct shear test on disturbed sample shows phi=30 deg and...
Hi everyone esp. Mr. PEinc who i've learned very much from him
My question is that a contractor has performed soil nailing in a slurry soil which water level is very high. they have done 4m but they want to go down to 20m but i dont think they can do that, could you please tell me what is the...
Hi everyone
I am new to this website, i've got a question and i would be very grateful if anybody can help me.
I wanted to test a soil nail for verification test, DTL was 100 kN, Bar dia=32mm with 4000 kN/m2 yield stress and unbonded length=9m, bonded length=3m, i applied 6100 psi pressure with...
