Does anybody know about the Sport field construction details? The Soil index properties and drainage layers?

Hi, take a look at journal of geotechnical and geoenvironmental engineering, ASCE, Vol. 127, No. 7, pp. 568-573. goodluck.

I have build a 2D model in ANSYS with PLANE42 element and elastic material property. I want those elements work only in compression,How can I do this in ANSYS?

A day i think too thanks

Focht3: thanks, i followed the steps, the clay has 35% free swell index, (highly expansive, swelling pressure at opt. water cont. was 265 kpa) by the way, do you think how much shall i wait to see the excess pore water pressure when i increased the confining pressure for B-value check? (2 mins...

gandersen: i know about back-pressuring technique but i am dealing with a high plastic clay, it is dense and it took 10 days to show 0.5 cc permeation by applying 150kpa gradient. how such plastic soil can responde to increase in confining pressure and shows up increament in pore pressure. have...

Does anybody know if B-Value can be obtained for HIGHLY PLASTIC compacted clays? how can i control degree of saturation for a soil which its hydraulic conductivity is about 10E-9 cm/s? any comments is welcome.

Hi All; I just want to know if anyone could help me on "Seismic Analysis of Reinforced Soil Walls". Any Libratory Data would help me.

would you please explain about 2.5 inches california ring?

hi ashjun i know a book named "waste containment facilities" by, D. E. Daniel , and R. M. Koernor published by ASCE 1995. other books from the above authors may be usefull. goodluck

Dear All Does anyboby know where can i find standard test method for measuring cation exchange capacity (CEC) and exchanchable cations (Na+, K+, Ca++, Mg++) awaiting

dear CHPaul what is LOI? thanks again

dear all does anybody know details about organic content determination of clay soils. i know the ASTM standard method by placing the oven dried sample into a stove with 440 to 750 c but how many hours should it be there? is 5 hours enougth or not? any more helps?

it really depends on your soil type if you have fine grained soil like CL or ML type the rate of test should not be more than 0.5 mm/min, for grater normal stresses (like 300 kpa normal stress) use smaller shear rate, the value of 0.3 to 0.2 mm/min is good. before starting the consolidation...

dear roso behavior of expansive clays are essentially related to their in-situ water content and compaction state (Dry density) and as UdayRB said to seasonal change of water content. if you are dealing with high plastic dry modarately high density compacted clay with change of ground water...

hi yahaira i thinks you have to look ASTM standards vol. 04.08 there is standard method for determination of specific gravity

dear msharief D422 uses material passed #10 for hydrometer analysis and i am in the idea that hydrometer analysis in material passed #200 after doing D1140 is more repreasentive for the clay fraction(<0.002mm) of soil. regards

select a repreasentive sample approximately 300 gr from your soil dry it in oven for 24 hour then weight it, then wash it from #200 put the remained in the oven for 24 hour and passed also. then seive the remained after 24 hour and use 50 gr of passed for hydrometer analysis. hydrometer analysis...

Dear Agus simply change the extension to *.cpd, your problem will be solved, but my models can not be used for pure bentonite. best Wishes

Dear All is there anyone knows about the standards for lining systems in heap leaching process in copper mines? i want to know about details of lining system such as clay barriers and filters and leach collectors,... Thanks 2 All
