1st Workshop “Geosynthetics for Slope Stabilization” @ World Landslide Forum (WLF) 2017 – Ljubljana, Slovenia, 01 June 2017

The 4th World Landslide Forum (WLF4) was held in Ljubljana, on 31th May – 2nd June 2017. As for the previous Editions, in Beijng (China) in 2014, in Roma (Italy) in 2011 and in Kyoto (Japan) in 2008, the event aimed to gather scholars and professionals of the various fields of Geotechnical Engineering, Geology and Engineering Geology. The WLF4 was jointly organized by the International Consortium on Landslides (Kyoto, Japan), the International Programme on Landslides (IPL), the University of Ljubljana and the Geological Survey of Slovenia. As a whole, the initiative gathered more than 400 oral and poster presentations, and more than 500 participants from 51 Countries.

The Italian Chapter AGI-IGS of IGS organized, for the first time within a WLF, a workshop for all the experts interested in geosynthetics applied to slope stability problems and landslides on 1st June 2017 at the venue of WLF4 in Ljubljana, in cooperation with the Slovenian Geotechnical Society of ISSMGE. The Chairmen were Daniele Cazzuffi (IGS Past President, CESI SpA, Milano, Italy) and Sabatino Cuomo (LARAM School, University of Salerno, Italy).

The interest of the 1st Workshop “Geosynthetics for Slope Stabilization” was related to the possibility that slope stability can be increased by geometry modifications, superficial or deep drainage, soil improvement, retaining structures or using geosynthetics. The increasing use of geosynthetics as reinforcing elements in soil structures – eventually associated with vegetation – has greatly encouraged sophisticated experimental work, including laboratory models and centrifuge tests, and advanced numerical analyses, in order to gain a better insight into the reinforcement mechanisms as well as to validate or improve the existing design methods. The reinforcement type, the soil mechanical properties and the anchorage system, as well as the extensibility, disposition and shape of the reinforcements lead to different behaviour in terms of deformation and strength. Geotechnical characteristics of the soil influence the stress distribution at the soil-reinforcement interface. The workshop was aimed to provide an opportunity to researchers and practitioners for sharing experience, ideas and best practices in the field of slope stabilization through geosynthetics and related products.

The program of the workshop was the following:

Mojca Ravnikar Turk, President of Slovenian Geotechnical Association: Welcome greetings and Introduction

Daniele Cazzuffi, Italy: The role of vegetation in geosynthetics-reinforced structures for slope stabilisation

Oliver Detert, Germany: High geogrid-reinforced slopes as flexible solution for problematic steep terrain: trieben-sunk project, Austria

Sabatino Cuomo, Italy: Recent experiences of geosynthetics reinforcement for unsaturated natural slopes in Italy

Zeljko Arbanas, Croatia: Geosynthetics in landslide remediation

Piergiorgio Recalcati, Italy: Geogrid reinforced slope 60.0 m high for the stabilization of the Valpola landslide

Vojkan Jovičić, Slovenia: The use of geotextile for the construction of tunnel portals
