Hi,
Please check the image above.
I have calculated the settlement until the surcharge is removed.
In the figure, there shows an elastic response of soil once the surcharge is removed.
How can you calculate the settlement just after the surcharge is removed(because the settlement is less...
Thank you for your reply.
But concrete is a non-Newtonian fluid, so the horizontal stress will be less than the vertical, but with which factor will it be reduced?
I mean with a k factor of some value.
Thank you HTURKAK for your reply.
Yes, I mean the tremie pipe.
The equation which you mentioned is for calculating the vertical stress, P =γ*H
But will the horizontal stress acting towards the wall of the tremie pipe will be the same as vertical?
Thank you all for your reply.
The pile is a full soil displacement pile without a casing.
Sorry, there was a mistake in my question that I asked before.
While the concrete is in the silo, before pouring it, how to calculate the horizontal stress of concrete acting towards the silo wall (pouring...
Hi,
When concrete is poured into the pile(for a fully soil displacement pile), in its fresh concrete stage, does the horizontal stress from concrete at a particular depth which is acting towards the soil will be less than the vertical depth at that level? If so, how to determine the horizontal...
Thank you for your reply.
Is there some kind of relation that exists to calculate the distance from the CPT probe to the magnetic object(like explosives etc) with the magnetic field measured from the CPT?
Hi,
How is it possible to calculate the distance of a magnetic object with the magnetic field measured by a magnetometer CPT (irrespective of the object direction).
Is there some relation that exists which can be correlated with distance to the magnetic object and magnetic field measured...
Thank you for your reply.
In Netherlands, they have derived an equation where you can calculate the chloride content from the electrical conductivity that measured in a CPT and the friction ratio...
Thank you for your reply. I do not know much about cpt testing. We do measure the electrical conductivity of soil in a CPTu test. And I have been asked to correlate the EC(electrical conductivity which is measured in mS/cm units) with Rf(frictional ratio), so that we can calculate the chloride...
Hi,
How can we correlate the electrical conductivity (EC) of soil (measured in a CPT test) and Frictional ratio (measured in a CPT test) to calculate the chloride content of soil?
Are there any articles that describe this relation?
I could not find one.
Please help.
Thank you for your reply.
I have searched for a lot. But I could not find any documents regarding a negative value for (qt-σvo).
And my negative values are not on the surface. It's in the soil layer below ground level at a depth of 8metres or 10 metres.
Since I get a negative value for (qt-σvo)...
Hi,
I need to calculate the permeability, k from cone penetration data.
The formula I have found is by calculating the soil behaviour type index, Ic , which is calculated from the normalised friction ratio (Fr) and normalised cone resistance (Qt).
The equations for calculating Fr =...
Thank you for your reaction.
FRom the wikipedia link, i have tried to solve it, but i am not getting the actual valuea.
Do you know how to do it in excel?
It will be really helpfull for me.
Hi,
I have an equation,
x*e^x = c(constant value)
How to calculate the value for x?
In the internet it says it is based up on Wlfraom equation.
And x= W(c)
But how to solve it?
Does any one know?
Thank you so much for your help.
But i am sorry beacuse still i couldnt get an equation for Ø
When Ω = 0 ,
0= 2π tanØ + 2tan [(45 + Ø/2] - LnC
In this above equation , Suppose C= 20, How to get a value for Ø
I need to get the Ø value in terms of C. There are still two Ø terms in this...
Thank you so much for your help.
But in the above comment, when we take log on both sides, tan2 is missing from your equation.
And also in the attached graph, according to De Beer, the equation is used on the condition that : when Ø´ is greater than Ø(provided). Inorder to find out this Ø´ i...
This is the equation for calculating φ' (effective friction angle) by "De Beer" method. In Belgium practice, they follow this method for calculating the pile bearing capacity. And i am in the starting stage of the calculation. I cannot go any further if i dont have an equation for φ'. I have to...
