Of the publication, NCMA writes:
This Guide reflects a compendium of contemporary
knowledge collected over several decades that highlight proven solutions using segmental retaining walls (SRWs). The information and recommendations presented in this Guide are intended to augment the design practices and recommendations contained within NCMA’s Design Manual for Segmental Retaining Walls, but are equally applicable regardless of the design methodology selected. The creation of this resource was driven by the establishment of NCMA’s Zero Failures Initiative–an industry-wide program to educate owners, designers, site civil engineers, geotechnical engineers, and installers of SRW systems on the industry’s recommended practices and to promote a philosophy that strives for ensuring successful wall performance.

Sponsorship included the opportunity for table top displays¸ along with a fifteen-minute time slot during meals to speak about projects that their companies had been involved with. Upon adjourning the seminar, Mr. Phaneuf expressed appreciation on behalf of the Division of Materials Management to the seminar sponsors (NAGS and GMA) for bringing this training opportunity to a New York State location and providing a venue where both regulators and design engineers have an opportunity learn together at a very reasonable cost.
Syracuse University Students w/Dr. Shobha Bhatia on the right next to the sign
“We found the technical seminar both comprehensive and enjoyable. As graduate students, it was stimulating as well as valuable to not only learn about the proper selection, design and construction of geosynthetic materials being used in today’s landfill liner and final cover systems but also be cognizant of the many reasons for failures encountered in real projects. The opportunity enabled us to widen our knowledge of the fundamentals when it comes to landfill engineering, design, and construction—while complementing that knowledge with the technological tools, techniques, and advances available to us today, as well as get the unique opportunity to understand the many regulatory concerns associated with each area of discussion.”
A comment from one of the regulators in attendance: “Simply the best professional technical training opportunity that I have had while being at the DEC”.

The 3rd Pan-American Conference on Geosynthetics (GeoAmericas 2016) will be held 10 – 13 April 2016 in Miami at the Loews Miami Beach Hotel. This quadrennial regional conference from the International Geosynthetics Society (IGS) features 3.5 days of high-quality geotechnical and civil engineering short courses, technical sessions, panel discussions, training lectures, keynote addresses, and networking in the international exhibit hall.
Mining is one of the conference’s cornerstone topics.
Geosynthetic materials are essential to the economical and environmental performance of mining operations. Geosynthetic technologies can be used to enhance infrastructure and improve processes. They provide more productive and robust facilities with higher yields.
Geogrids efficiently improve the integrity of unpaved access roads to prevent costly failures under heavy loads and in poor weather.
Geomembranes increase the yield and flow from heap leach pads and liquor trenches.
Geotextiles, geocomposite drainage materials, geosynthetic clay liners, and other geosynthetics perform vital functions, enhance drainage and venting, improve the stability of berms around tailings, etc.
Attendees of GeoAmericas will learn why soil reinforcement is more important than ever to the success of mining and how geosynthetic liners and covers have dramatically and beneficially changed the economics and performance of heap leaching for gold, copper, uranium, and other materials. With multiple courses and sessions to draw upon, GeoAmericas gives participants ready-to-use strategies and access to geosynthetic designers, suppliers, and installers from throughout the Americas.
Highlights for mining professionals include:
Keynote lecture by Dr. Robert Koerner on “Lifetime Predictions of Exposed Geotextiles and Geomembranes”

Geosynthetic materials are used extensively in coastal protection projects. The modern geotextiles industry, in fact, emerged in the 1950s in response to flooding in the Netherlands and tropical storm damage in the United States. Since then, a large industry and innovative coastal designs have come along. Geosynthetic tubes and containers provide dewatering and solids separation for large-scale dredging operations and the construction of artificial islands. They build up dune systems for hurricane defense and create artificial reefs. Geotextiles and affiliated gabion systems provide shoreline stabilization and erosion control. Geosynthetic bags provide scour protection for shorelines, infrastructure (e.g., ports), and even off-shore wind turbines. Geosynthetics reinforce levees, enhance the sustainability of waterfront construction, and provide highly effective, economical solutions to long-term coastal engineering goals.
GeoAmericas 2016 features multiple opportunities for coastal protection professionals. Just some of the technical offerings well suited to engineers working in coastal protection include:
Training lectures on embankments on soft soils

PROBLEM DESCRIPTION & AVAILABLE DATA
A geotextile-reinforced prototype mechanically-stabilized earth (MSE) wall was constructed using wrap-around facing with a width of 4m, a height of 4m and a length of 4m. The wall was built with 10 geotextile layers evenly spaced at 0.40m vertically. The reinforcement length was equal to 3.0m. The MSE wall was constructed atop a firm foundation that can be assumed to be rigid with first geotextile layer placed at the ground level. In the design, the reduction factors against creep, durability and installation damage were taken as 1.0. The wrap-around system was assembled using metallic supports and wood boards, for a final angle of 78o from horizontal, resulting in a face slope of 5V:1H. The geotextile material used in the wall was a short-fiber needle-punched polyester non-woven geotextile with the following characteristics:
Backfill soil consisted of a fine to medium well-graded sand which was compacted using a vibratory plate hammer. The grain size distribution of backfill soil is presented in Figure 1. The maximum and minimum void ratios, emax and emin were 0.70 and 0.46. The backfill soil was compacted to a target relative density of 80% which corresponds to a void ratio of 0.51 and dry unit weight of 17.7 kN/m3. The backfill was placed in the field at a gravimetric water content of 5.0%. The soil has a drained friction angle of 33°.
Goal
Estimate the deflections of the wall face as a function of wall height due to the wall’s self-weight immediately after construction.
