In an open letter to geotechnical engineers and agencies that specify geosynthetics on their projects, the Geosynthetics Manufacturers Association (GMA) has requested that specifiers use the correct standards when referring material properties of geotextiles and other geosynthetics. For example, they refer to two standards that are now out of date, The Mullen Burst Strength and the Puncture Test which were both originally designed for paper. The correct standard is the Static (CBR) Puncture ASTM D6241. See the entire letter on Geosyntheticsmagazine.com. (Photo of Geotextiles from Nilex.com)
TenCate geosynthetics was a textile technology company in 1953 when disastrous flooding struck the Netherlands. The company came up with some of the first applications of geosynthetics that allowed the creation of the Oostershelde Flood […]
The Deep Foundations Institute is accepting scholarships for undergraduate and graduate students in geotechnical engineering or foundation engineering at a U.S. college or university. The at-large scholarships range from 2,000 to 5,000. For more information […]
In this part 2 of 2, various types of retaining walls are examined as possible alternatives in a side-hill retaining wall situation. These include conventional wall types such as CIP walls, MSE walls, gravity walls and soldier pile walls and some less conventional approaches such as lighweight concrete fill, hybrid soil-nail and geofoam wall systems, ground improvement and micropile walls.
Part 1 of this Side Hill Retaining Wall article covered the definition, significance, problems and failure modes, investigation techniques, analysis, and construction considerations of side hill walls.
