I have a corrolary question to CVG's latest comment. How does one determine the "extension" distance of the mat in lieu of an anchor trench? I have a large sewage lagoon (800 ft across) that is scouring one bank from wave action. The level is relatively constant until the summer...
Both are excellent, relatively new technologies that offer potential solutions in certain applications that may be less expensive alternatives than more conventional solutions. Do your research and read up on case histories, etc. I've seen geopiers used successfully in a variety of conditions...
Has anyone done a quick estimate of the additional water pressure against the wall? Wouldn't it be simply a triangular stress distribution of the unit weight times the height of soil against the wall (assuming fully saturated ground conditions)? With a 4 foot high wall and assuming 6"...
Just to throw in my two cents, I purchased GSlope about a year and a half ago and I love it. Modeling soil slopes and various retaining wall applications (with geogrid or tiebacks) is very easy and intuitive. You can download a full trial version and see for yourself. Hint: there are some...
JDMM,
I'm curious as to which SRW system was used for this project and where it was built. That's a monster of a wall! Do you know what kind of reinforcment was used?
I've had excellent experiences doing segmental retaining wall design. In fact, that's what I do! You need more information before you proceed.
Simple gravity wall systems (stack-'em-up blocks) almost never can go to the height you are talking about without additional reinforcement.
The most...

Sound advice for DCP, although I'd feel better makng a guess while I'm looking at the DCP data rather than a blind guess. I'm interested in a different MR, Resilient Modulus - not modulus of rupture. AASHTO uses it in their pavement design procedure. The actual test procedure is so...
Along the same line, I'm looking for a correlation between SPT values and Resilient Modulus. Perhaps a correlation from SPT to CBR, then Mr=1200XCBR (or Mr=1500XCBR)?
