Hello fellow geotechs, My name is Deb Miller. I am a consulting engineer in Colorado, USA. I am currently working on the design of a new, 43 m high embankment dam situated in some very challenging geology in southern Wyoming. One of the interesting foundation challenges on this project is the presence of shallow, downstream-dipping weak bentonitic clay beds in the valley section, which tend to act as great aquitards so that pore pressures are as big a potential problem as low shear strength. I look forward to observing and participating in your group's discussions, and will have some questions prepared soon regarding my dam (damn?) project that I hope members of the group may have some insights on.
