I'm currently developing a design for a large dam founded on thick, heavily overconsolidated, pre-sheared marine clays. The residual strength of the foundation material is very low - experience in the area uses friction angles of 8 to 12 degrees for design.
Our standard practice is to use...
Hi All,
I have a series of data (residual direct shear results - normal stress vs. shear stress), and have plotted the data in Excel. I'm trying to find a way to automate the process of determining the friction angle based on the data, bouning it by the 95 percentile lower bound. I can do it...
I was just thinking back to my previous employer. When it came time to review salaries, my supervisor would ask us to keep our new salaries confidential from the other employees. Personally, I didn't see an issue with this - I feel my salary is my own business. However, I had a co-worker who...
I am looking for a database that can be used to manage geotechnical lab data (everything from moisture content to direct shear to triaxial results). We have a large mine site that will eventually have a very large data set, and would like to implement something that allows searching based on...
I am faced with a problem that I don't know the answer to. I am trying to determine how pressure dissipates through a soil, not with respect to time, but with respect to distance.
Say, for example, a soil with an initial pore pressure, is injected with a higher pressure at a point source (i.e...
Hi All,
I recently started with a new company, and their CAD standard is AutoDESK Map 3D 2007.
I have an annoyance that I don't know how to get rid of. Everytime I pan, or zoom, when I repeat the last command (i.e. right click), it tries to repeat the command MAPUICMDPICKSET, rather than the...
I'm wondering if anyone has a list, or knows of a website that has a list, of Geotechnical-related conferences/workshops in North America. I'm trying to put together a "wishlist" of conferences that I would like to attend (and for others in my Geotech group).
Thanks...
I am in discussions with a consultant who likes to use Spencer's method for slope stability. I know generally about the method (uses force and moment equilibrium), but I've never used it in practice. I am however quite familiar with Morgenstern-Price methods. Has anyone compared the methods...
Folks...
A general interest question came up the other day in conversation. What would be the effects related to nuclear density testing (i.e. Troxler) in a stockpile of a hydrate material (for example, gypsum). I would imagine that the hydrate nature of the material would impact the density...
Hello All,
I'm looking for some good resources to migrate to Microstation/J. I've always been an AutoCAD user, but I now need to switch as my employer now uses Microstation/J.
Thanks!
Hello fellow Geotechs,
I am currently looking to purchase a new slope stability package for our firm. We currently use Geo-Slope Slope/W, and also have GSlope. I was wondering what experience folks have with other stability analysis software. One key item we would be looking for is a better...
