An article by Eric and Dan on the use of micropiles for slope stabilization has been added to our Publications Page. Published in the August 2010 issue of Foundation Drilling Magazine, the article summarizes key findings and recommendations from a study that reviewed and evaluated existing micropile design methods. A new design method is proposed to better predict the mobilized resistance of micropiles used for slope stabilization. The full report prepared by Eric and Dan for the joint ADSC/DFI Micropile Committee, “A Method for Predicting Mobilization Resistance for Micropiles Used in Slope Stabilization Applications”, presents the details of this study. Robert previously posted about this report here.

Last week’s International Foundation Congress and Equipment Exposition was a huge success! Dan gave a keynote address on Tuesday on managing risk in deep foundations within the design-build delivery model. Paul, Erik, and I also had papers to present. The technical sessions were excellent, the indoor exhibits were excellent, and the outdoor exhibits of foundation equipment were outstanding! The ADSC, Geo-Institute, and PDCA were the co-organizers of the event. A big hats off to all of the staff of all three organizations that made the event a huge success! Thanks and “atta boy” go to Mohamad Hussein, P.E. (Conference Chair) and to Dan (Technical Program Chair) for all of their work, as well as the rest of the organizing committee. I have also blogged about the conference here at GeoPrac.net. Here are some pictures of the outdoor exhibits:
There were over 300 papers included in the conference. The proceedings were published as three Geotechnical Special Publications: GSP 185: Contemporary Topics in Deep Foundations GSP 186: Contemporary Topics in In-Situ Testing, Analysis, and Reliability of Foundations GSP 187: Contemporary Topics in Ground Modification, Problem Soils, and Geo-Support The editors, Magued Iskander, Ph.D., P.E. (Polytechnic Institute of New York University), Debra Laefer, Ph.D. (University College Dublin, Ireland), and Mohamad Hussein, P.E. (GRL) all had their work cut out for them. I have added all seven papers authored by DBA team members to our site. The links are below, or you can go to our Publications page.

Well, the ADSC 2008 Faculty Workshop Field Day was a great success! A group of 46 civil engineering faculty members from across the country participated in the week-long workshop that culminated in a field demonstration day at the World Headquarters of Dan Brown and Associates in Sequatchie, Tennessee. The participants and instructors were treated to installation and testing demonstrations of drilled shaft foundations, micropile foundations, and anchored earth retention systems. The load tests included a static load test of a micropile and a Statnamic test of a drilled shaft, which provided some of the day’s excitement. Installation demonstrations of the various drilled foundations and anchors allowed the participants to observe how the various elements are installed. Even though we had to dodge an occasional thundershower, everyone had a great time and felt that they went away with a lot of valuable information for their classes back home. More info on the Workshop here. I put together a slide show of photos taken by myself (Robert) and Dr. Erik Lohr. |
