Recording Geotechnical Drill Rig Parameters PDF Print E-mail

Geotechnical Drill Rig

Providing geotechnical drilling parameters such as thrust, rotation, rate of penetration, and flush pressure will soon be incorporated into European Standard EN22574-15 and is already in BS5930. Having these parameters available gives geotechnical engineers another tool in the toolbox to characterize the subsurface. But I am not familiar with any drilling companies here in the US that can record and report this type of data. Does anyone use this technology in their practice? What kind of equipment is required on the drill rig to collect this data? Leave a comment, or tweet @geoprac.

Top Geotechnical Engineering Programs in the US

What are the top geotechnical engineering schools in the United States? I don't know how accurate or scientific this list is, but a quick glance tells me they definitely got many of the most well-known programs. Their list was based on the top Civil Engineering Programs (according to US News and World Report) that also offer geotechnical engineering programs. I doubt the person who compiled this knows much about geotech. But if you are a student researching where to go get a MS in geotech, this list is a good place to start. Anyone care to comment?

Example historical USGS topo map of Highlands, TX from 1912

Esri announced earlier this summer that they were making over 175,000 historical maps from the USGS available online. The maps are available to anyone to view online using their web map viewer. Or ArcGIS online subscribers can have access to high-resolution geo-referenced raster images for use in their ArcGIS projects and web mapping projects. Very cool!

Liebherr's foundation drill rig equipment simulator in action

Equipment manufacturer Liebherr has created a new simulator to allow operators to train on foundation drilling equipment virtually. The simulator is based on other simulators created by Liebherr, and includes things like a real construction site with neighboring buildings and structures, uneven ground, varying soil conditions, etc. [Source: Read more at GE Innovation News | New Civil Engineer via @GE_magazine.

2014 Terzaghi Lecture - Carlos Santamarina PDF Print E-mail

Tuesday, 01 July 2014 00:14

Dr. Carlos Santamarina of Georgia Tech. presented the 2014 Terzaghi Lecture at Geo-Congress 2014 entititled 'Energy Geotechnology: Enabling New Insights Into Soil Behavior'. From the You-Tube summary:

Energy is critical to life, and the coming decades will see worldwide population growth and associated economic development that will result in a pronounced increase in energy demand. Historically, geotechnical engineering has been crucial to projects that have sustained societal transformations. Once again, geotechnical engineering has a central role to play in the evolving energy challenge, from resource recovery and infrastructure development, to energy storage and waste management. Examples during this lecture and details in the accompanying manuscript show that the emerging field of energy geotechnology drives us to reconsider the basic tenets of geotechnical engineering (such as soil formation, index properties, and classification), to extend our understanding of geomaterials (at high pressure and temperature, long time scales, and large number of repetitions), to recognize new phenomena (most often couplings between hydraulic, thermal, chemical, biological and mechanical processes, and various forms of localization), and to advance technological innovations for characterization (in situ, sampling, and laboratory) and monitoring.

APE Pile Driving and Helical Pile Introduction Video PDF Print E-mail
Written by Randy Post   
Sunday, 09 March 2014 23:14

I met a gentleman from American Pile driving Equipment, or APE, on the plane on my way to the GeoCongress conference. We spent some time chatting, and we visited at the trade show at the conference too. I've mentioned APE on GeoPrac before, you might remember the 'Octakong' pile driving hammer, made of of 8 individual but synchronized hammers used to drive 72' diameter piles for the Hong Kong-Zhuhai-Macau Seaway project. I was impressed with a helical pile system they have developed that can be installed using an excavator mounted system and even pressure grouted into place. They also have down the hole hammer attachments to help pre-drill the holes in hard soils. Check out the video below for more about APE and the helical pile system.
