ADSC Joins with FHWA to Conduct Hollow Core Soil Nail Research

September 10, 2007 rockman Comments Off on ADSC Joins with FHWA to Conduct Hollow Core Soil Nail Research

The ADSC [Editor] (Association of Drilled Shaft Contractors) [/Editor] will join the FHWA as co-sponsors of a research project to develop a database of the available grout-to-ground bond stress of Hollow Core Anchors (HCAs) and to determine if correlations exist with traditional solid bar, drill and grout soil nails. The FHWA and the ADSC are interested in documenting the performance of HCAs in soil nail wall type construction and identifying methods of quality assurance so that HCAs can be specified with confidence in appropriate applications, both temporary and permanent.

Server Problems

September 9, 2007 rockman Comments Off on Server Problems

Last thursday-friday was not a very good one for me. Sometime between 10 and 11:30am on thursday, the server hosting GeoPrac and a number of my other websites and those of my clients went down. I was on my way up to Phoenix for meetings, so I didn’t know about it until I got a call from my office that the email was down at about 4pm.

I got online and couldn’t bring up the website of my hosting company. I did a blog/bulletin board search to try and find out what was going on since I figured there were a bunch of other people effected by this as well. The first page I found just had posts from other people like me, trying to figure out what was going on. But there was a link to another thread, and I knew i was in trouble when I saw that it was page 1 of 24! [more…]

Engineering Geology in World War 1

August 21, 2007 rockman 2

People (including myself) tend to forget the origins of the term "Land Mine". Mines in medieval times referred to excavations for the purpose of undermining an enemy’s fortifications. In World War 1, before the age of aerial bombardment and cruise missiles, underground mines were used to plant explosives under enemy lines. In addition to British, German and American sappers that performed these tasks, the Australians had a contingent of miners and geologists who were involved in the Western Front of the War in France and Belgium and were responsible for what was then the largest man-made explosion in history. I hope you enjoy this interesting article. Thanks to Geology.com for the link.
