On June 11, 2002, a 150-foot wide and 60-foot deep sinkhole opened up in Pine Hills, Florida and came within a few feet of two 3-story appartment buildings. Geotechnical and Environmental Consultants (GEC) was contacted by the owner of the site to design emergency temporary and permanent stabilization measures to protect the buildings. The sinkhole mitigation began with a chemical stabilization of the soil using an injected sodium silicate chemical grout (incidentally, that work was performed by John N. Puder, Inc., recently acquired by Moretrench) to stabilize the sands underneath the buildings and adjacent to the sinkhole. After some GPR surveys, borings and other investigations, final sinkhole repair consisted of a 200-foot long wall omprised of interlocked 36-inch diameter steel tubular piles that extended to a depth of 50 feet. They were driven by Giken America Corp. using the press-in method which helped to avoid damage to the adjacent buildings. The entire stabilization was completed within 1-month of the initial sinkhole collapse! Click through for this fascinating video. (Photo credit Giken America Corp. by way of GEC)
This month there is a new standard related to nondestructive testing, revisions for several standards involving aggregates, cements and mortars, and the standard test method for expansion index of soils. Click through for the list.
ADAMA Software has released update 9.2 for their Mechanically Stabilized Earth retaining wall design software, MSEW 3.0 as of December 12, 2008. They also released update 3.1 for ReSSA 3.0, a reinforced soil slope design program on January 15, 2009. The ReSSA update seems like a relatively minor one, but the MSEW update contains a number of updates related to AASHTO LRFD resistance factors and design methods. If you are involved in MSE wall design for highway structures using LRFD, be sure to click through for a few highlights from the update and the download link.
