I have samples of clayey sand and clayey gravel (weathered granite) that I want to test for permeability. Which method should i do - falling or constant head?
Does anyone have any advice for the founding conditions for a high resolution electron microscope. We have encountered shallow quartzitic rock in test pits. The conceptual design is to place a 1m thick RC base on 350mm sand. Anything we sould be aware of? How do we determine severity of ground...
Can anyone tell me how to calculate predicted settlement from oedometer tests (e log p curve). I know how to calculate the collapse with the formula((eo-e1)/1+eo)*100. But dont know how to arrive at total settlement.
Hi there guys,
I have acquired a hand held shear vane made by "Controls" but dont have an instruction manual and all attempts to get this from the manufacturer have failed. I have seen one in operation before and understand the basic theory but maybe one of you have experience with these devices...
I am trying to come up with a practical method of sealing off the underflow under a proposed new weir in a very inaccessible gorge. I dont know the depth of the rock and the river bed is filled with large boulders. Do I drill & grout or what?
