Deep excavation software

Deep Excavation, LLC has an excellent blog post on how geotechnical engineers should provide geotechnical parameters for use by a shoring designer. Mr. Konstantakos notes that most of us geotechnical engineers provide only lateral earth pressure parameters, but there are a number of problems with that approach. Today's shoring designs are much more complex, requiring staged analyses and service limit analyses that you simply can't do if all you have are basic parameters. So what should you provide in your geotechnical reports? Go read the post to find out! [Source: Deep Excavation. Image: DeepExcavation.com]

Contaminated soil remediation by Moretrench

Excavations in an urban environment often encounter contaminated soil and/or groundwater. GeoPrac sponsor Moretrench is an expert in geotechnical construction methods for preventing the contamination from entering or leaving a site. In a recent blog post, Moretrench highlighted four construction techniques for meeting these objectives. They are: slurry trenches, jet grouting, permeation grouting, and ground freezing.

GRS-IBS Guide Specifications

This guide was issued to provide guidelines for construction of the geosynthetic reinforced soilintegrated bridge system (GRS-IBS). Refer to Geosynthetic Reinforced Soil Integrated Bridge System Interim Implementation Guide for GRS-IBS design and construction guidelines. This guide serves as the technical basis for agency-developed standard specifications. Local experience and practice should be incorporated as applicable. [Source: FHWA. Image: FHWA]

Deep Excavation's Geotechnical Activity Index chart as of October 2012

Deep Excavation, the makers of shoring design software, DeepXcav, are reporting on the Geotechnical Activity Index, that they describe as:

The geotechnical activity index is a new index that reports on the geotechnical potential in each State within the US. The index takes into consideration the geotechnical activity and population in each state. The main objective is to track changes over time in geotechnical and foundation works.

This is some really interesting data to look at. I'm curious what the source of the info is. Maybe we can get Deep Excavation Founder and CEO Dimitrios Konstantakos to give us a little hint! [Source: Deep Excavation. Image: Deep Excavation, LLC]

APE develops Helical Pile systems PDF Print E-mail

APE large diameter helical piles, a relatively new deep foundation alternative

Well-known pile hammer manufacturer APE has purchased technology for driving and coupling large diameter helical piles that could help make this technology more mainstream. Rather than pounding the pile into the ground, the steel drill pipe casing is rotated using patented couplers in a way that reminds me of a giant socket wrench or an Allen wrench. The base of the pile can be post-grouted, or grouted during installation. APE notes that this technology is ideal for environmentally sensitive areas where pile driving is not an option. Piles up to 42 inches in diameter have been successfully installed and load tested. [Source: APE News. Image: APE]

TenCate Geoport geotextile tube-filling system

Geotextile tubes are filled by pumping material in slurry form into the tube to form structures that can be used as breakwaters, levees, or other containment structures. TenCate has a new product that much improves what was a weak point in the system, the connection between the geotextile tube and the injection system. Their newly-patented Geoport mechanical injection system reduces stress at the injection point, and makes sure that the final closed connection is as strong as the geotextile itself.
