    Creep of Froth-Pak and Handi-Foam

    Hello, Does anyone know where I can find data on creep behavior of Froth-pak and Handi-Foam? I've tried their respective websites, but have had no luck. Thanks,

    Borehole Collapse

    Can anyone suggest some references or formulas for determining when borehole collapse will occur when drilled in certain type of rocks? I am trying to figure out at what depth will I need a liner if at all. Thanks

    Soil Arching

    Hello, Can anyone give some references to effects of soil arching on underground openings. I am trying to figure out when soil arching becomes a factor, at what depth does soil arching begin to aid in reducing the overburden pressure (of soil and a surcharge)above the tunnel. I am looking at...

    Using Air Pressure to Stabilize Tunnel

    Fellow Engineers, I am researching the feasibility of using air pressure to stabilize a tunnel during excavation. The tunnel is small in size, not very deep (5') and the soil unit weight is about 107 pcf, sandy clay. This will be a temporary solution until a permanent structure can be built...

It requires the thrusting of specially developed curved metal plates at a specified length and width, into the soil, then continuing to attach each link until an arc forms and a tunnel is created, then it is excavated, with the...

    I think it's going well. I have aggressively completed review of both of Das' books(one covering principles of geotech and the other foundations) including all the end chapter problems. I have also gotten a hold of a Geotech PE review book from Soilstructures.com by Liban Afii. I have found it...

    HELP...Geo PE References

    Exactly my feeling, I have been doing all the chapter problems in the "Principles of Foundation Engineering" by Das 5th Ed. I plan on doing as many problems as possible. I'll definitly pass this time around. Thanks to you all for your suggestions, I have found them very helpfull.

    HELP...Geo PE References

    Harney, I just purchased "Principles of Foundation Engineering" by Das 5th Ed. I have enjoyed it so far. My only complaint is that like many texts, they only provide answers to the odd questions, nothing on how they got to the answer. On some of the problems, I am almost 100% sure I am...

    HELP...Geo PE References

    hello, I just got my results back from the April 2004 PE, I did Geotech in the afternoon. I got a 67 overall, but my foundation and retaining wall scores were very disappointing. I do not have any references for the Geotech part, just the Lindberg reference book. Can anyone recommed good...
