I am desiginig Retaining walls. Which pseudostatic force shall I use the basic acceleration in rock or the máximum acceleration of the spectrum.
Does AASHTO include any reduction of this force/acceleration?
Kind regards
How do i take into account the swelling pressure of clay on my retaining wall?
I have 4 meters of active clay but how do I estimate the swelling pressures on this 4m. I have seen some publication in which in for the first 0.5m to 1m the swelling pressure is taken as the Passive Earth...
I am a modelling with a 3D numerical model a footing in which in on one of the load combinations and due to the high moment it has one of the sides in tension and therefore the footing separates from the ground (Gapping).
Of course that this could be mitigated by having higher vertical loads...
Hello everyone.
I am doing some calculations of a Soil Nail Retaining wall in which the Soil Nails are skewed to 45º.
For the 2D Limit equilibrium calculations I am using the projected length of the anchor (multiplying the length by cos45) and I guess that I should also multiply by cos45 the...
Good morning,
Any experience in doing cylic triaxial testing on rock samples. I would like to know the cyclic degradation of rock but It is hard to find any method specification. Any clue on usual % of rock degradation?
Thanks
Yes I agree with you, the material that is going to be dredged is clayey silt/Sandy silt and It makes sense that when the cell is filled it is is going yo behave as a liquid so i believe that two hypotheses could be checked:
1)Calculation of horizontal stresses on the cell wall considering that...
Hi everyone,
Our client wants us tu evaluate the earth pressures due to the caisson fill. We have always use granular backfill with the usual narrow backfill theory (silo effect). However with a cohesive fill from a dredge can we still use the narrow backfill theory?
Many thanks
