Site Updates – Feeds and links added, new staff photo!

I have added a feed to the Geoprac.net blog site. I have also added a link to the latest issues of the Geoengineer.org newsletter. Both of these are on the right sidebar of the site.

We finally got a picture of Steve for the “About Us” page of the site, for those of you that may have been wondering if he really existed or not. CHECK IT OUT!

Link added to Loadtest, Inc.

We have added a link to Loadtest, Inc.,developer of the Osterberg cell (now commonly called the O-cell) test device for drilled shaft and foundation load testing. They have been providing O-cells for the loadtests at the John James Audubon Bridge in Louisiana. Results of those tests will be published ion the near future.

Publications on IGM (intermediate geomaterials) added to site

I have added a couple of publications to the site that cover intermediate geomaterials, or IGM. The first is a paper Dan and I published from my master’s thesis in 1994 which I presented at the 25th Ohio River Valley Soils Seminar in Lexington, Kentucky.: The second one is a report of axial and lateral load tests for drilled shaft foundations in shale for a bridge in Alabama. The loadtests, analysis, and design recommendations were done as part of a research project on drilled shafts Dan was doing for ALDOT. My thesis work was part of the research project.

I am slowly working on getting as many of our publications on the site as possible. Thank you for your patience!

Thompson, W.R. and Brown, D.A., 1994. “Axial Response of Drilled Shafts in Intermediate Geomaterials in the Southeast,” Recent Advances in Deep Foundations – Proceedings, Ohio River Valley Soils Seminar XXV, Lexington, Kentucky, pp 3-1 – 3-10.

Tip grouting research paper added to site

I have added a paper on tip-grouting of drilled shafts to the site. Steve was coauthor with Dr. Gray Mullins, P.E. and Danny Winters of the University of South Florida. The paper was published in the April edition of the ASCE Journal of Geotechnical and Geoenvironmental Engineering.

Mullins, G., Winters, D., and Dapp, S., 2006. “Predicting End Bearing Capacity of Post-Grouted Drilled Shaft in Cohesionless Soils,” Journal of Geotechnical and Geoenvironmental Engineering, Volume 132, No. 4, ASCE, pp478-487.

Link to GeoPrac.net added

I have added a link to GeoPrac.net, a new website in the on-line geotechnical community, under our Geotechnical Resources side bar on the left. The site has been started by Randy Post, P.E. of NCS Consultants. From the site: “GeoPrac.net is a community site for practitioners of geotechnical engineering, geological engineering, engineering geology, hydrogeology and related disciplines.”
