Website links, new publications in geotechnical engineering and engineering geology and Google Earth related information can be found in this section.
These geologic maps just released from the California Geologic Survey mark the 150th anniversary of the CGS. They can be viewed online in a very easy to use Google Maps interface. The previous Geologic Map […]
Hot on the heals of the revised MSE Wall Manual, the FHWA has released another manual, this one on Spread Footings. Selection of Spread Footings on Soils to Support Highway Bridge Structures was authored by Naresh C. Samtani, PE, PhD, Edward A Nowatzki, PE, PhD and Dennis R. Mertz, PE, PhD. So what is this manual all about? I think the foreword by Scott Anderson, PE, PhD of the FHWA Resource Center says it best:
The much anticipated LRFD update to the MSE Wall and Reinforced Soil Slope Manual is now available for download from the FHWA’s website. The full title of the document is Design of Mechanically Stabilized Earth Walls and Reinforced Soil Slopes and it was authored by Ryan R. Berg, P.E.; Barry R. Christopher, Ph.D., P.E. and Naresh C. Samtani, Ph.D., P.E. Find the abstract and download link below. As time permits, I’ll try to post more about some of the changes in this important geotechnical publication.
At GPSWorld.com in the Defense / Warfighter category, Don Jewell posted a very nice review of the Trimble Yuma Rugged Tablet PC. Jewell is a 30-yr veteran of the Air Force, involved in GPS systems […]
Geotextiles are frequently used for subgrade improvement under roadways. Caltrans has released a document titled "Guide for Designing Subgrade Enhancing Geotextiles". This 18-page document covers what situations can be improved using geotextiles and includes a […]
I introduced this ruggedized field tablet PC by Trimble here back in March, but there wasn’t any pricing information available at that time. To refresh, it has a military grade ruggedized design to keep out dirt and water, 32GB solid state drive (no moving parts), built in GPS, Wi-Fi, bluetooth 2.0, 2 integrated digital cameras with geotagging functionality (why 2?), Windows Vista Business, and a 7″ sunlight readable screen all in a 2.6-lb package. Read on for the $$.
At the end of last month, the Oregon Department of Geology and Mineral Industries (DOGAMI) issued this press release describing their new online interface for their statewide digital geologic map. The online version only covers […]
SlashGeo pointed me to LandSerf, an interesting bit of free GIS software (not open source) for viewing and analysis of DEMs, TINs, and other files in 3D. It uses OpenGL for the 3D graphics, and […]
UC Berkley has a bunch of lectures online, including three geoengineering themed ones. It appears that they were all from lectures given as a part of the 27th Annual GeoEngineering Distinguished Lecture Series on May 8, 2009. So if you have an hour plus to kill per lecture (and I haven’t yet), you can check out one of the following.
Hillsborough County Florida is using a mix of expanding polyurethane foam and conventional cement grout as a more cost effective means of filling sinkholes. Officials say the mix uses 30 to 40% less grout adding […]
