Thanks for your answers! I forgot to say that pipe is made of steel

Hello, we have to install 2 pipes (100 inches each other) in a swamp area (soft clays with water level 1.5 m below ground). The trouble is that the client wants to install a layer of gravel or crush rock above the pipes for avoid the buoyancy. I don´t believe in that system because it could...

Thank you for your answers. Geopavetraffic, firstly, we need some data about compaction characteristics because there are no data; secondly, the earth dam is very small, so the program wouldn´t be very expensive (5 borings). I had thought to follow a similar steps like yours. Ron, I know it...

Hi! We have a earth dam and we need to know some values of Modified Proctor because it doen´t exist any data before. Is useful to extract samples from the current earth dam for determining it? I think that it could be useless cause that material is already compacted. Thank you.

Could you consider a geophysical techniques instead of down-cross hole? It is cheaper, quickly and more reliable; a good method is passive seismic (ReMi).

Hey guys, I have a little problem. I am studying a case of a earth dam which were constructed two years ago(without filling water until now), and I have to make the stability anaylisis;firstly I carry out several boreholes and piezocones up the fill. This is formed with CH clays (it seems not...

Hi, I have a problem. We have to propose a solution in a area which is gained to the sea. There is a sector which is constructed 4 oil/water tanks (with a load of 1,2 and 2 kg/cm2, respectily). The fill is composed of gravel and sand (USCS, GP-GM or GW-GP),mainly. It has a average thickness of...

Do you know any case about a important creep in marls (as foundation of a embankment dam) ? Thanks

hi, i have a little problem, We have to construct a earthfill with expansive clays, because it is the only material in the area for use. What do you recommend to construct the little dam with this type of material? How can I isolate these? Thank you very much for your help

What type of wall or method I could use for retain 21 meters of filling? I think it´s impossible to use anchors or something.Is it possible prefabricated structural elements? Do you know any case? Thank you

What do you think about the values of pressuremeters for piles foundation? Are very overestimated in deep clays, concretely in marls in comparation with laboratory tests? I have any problems with the values when I apply these in the COAM formulation and the pressuremeters formulation. Could...

I am going to work with pressiometers and I´d like to know some web page or pdf manual about them. Thank very much.

Do you know any web page or manual about foundation of skyscrapers in special conditions (below phreatic level, founded in expansive clays, etc ? Maybe this year I have to work with it and I´d like to know more about this. Thank you very much.
