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,
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
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...
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...
Hello,
I am looking into a method of tunneling that is new to me. 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...
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...
