Maccaferri and Gouw Tjie-Liong present together at the GeoAsia 2016 conference

GeoAsia 2016

The presentation discusses a paper on the use of a High Hybrid Reinforced Soil Slopes as Runway support at the Tana Toraja Airport

Maccaferri is participating at the 6th Asian Regional Conference on Geosynthetics that is taking place from the 8th to the 11th of November of this year with a presentation on a case-study of Hybrid reinforced soil slopes used for Runaway support at the Tana Toraja Airport. The paper was written in collaboration with the Geotechnical Consultant Gouw Tjie-Liong.

The 6th Asian Regional Conference on Geosynthetics (GeoAsia) is taking place on the 8th of November to the 11th of November of this year at the Maenekshaw Centre in the Cantonment area of Delhi. The main theme of the conference is “Geosynthetics for Infrastructure Development”. The event provides opportunities for the exchange of experiences, practices and collaborations to facilitate flow of appropriate technology to enable successful implementation of infrastructure projects. Sub-themes of the conference will include:

The Maccaferri team will deliver a presentation on a case study discussing the use of High Hybrid Reinforced Soil Slope as Runway Support at the Tana Toraj Airport, written in collaboration with the Geotechnical Consultant Gouw Tjie-Liong

The presentation will elaborate on how and why the use of hybrid Reinforced Soil Slopes combining anchored gabion units and high strength geogrids for infrastructure development is growing in Indonesia. Hybrid RSS are considered to be a valid and competitive alternative to other traditional earth retaining structures.

Despite this growth, civil engineers and construction companies are not yet familiar with the related design and construction aspects. With this case study, Maccaferri’s team aims to share the processes, challenges, development and design life of a 25 m high hybrid RSS for the new Tana Toraja tourist airport (Sulawesi, Indonesia). It is worth noting that the RSS was built on soft and weathered clay shales and cohesive backfill materials were used as part of the reinforced soil mass. Maccaferri presents the main technical issues related to the project, the design process, which was carried out using both FEM and Limit Equilibrium Method software, and the relevant construction aspects.
