Design and Construction of a Very High Embankment Using Geosynthetic Reinforcement
Kannur International Airport Ltd. (KIAL) is a new Greenfield airport project with airside development on an undulating terrain with an average height of 90 m above mean sea level (MSL) and a maximum height of 142 m. To accommodate the desired Runway length and runway end safety area (RESA) at both the ends along the proposed alignment, it resulted in 45.5 million cubic meters in cutting and filling. The insufficient availability of land for the construction of free slope embankment at RESA 07 end resulted in the design and construction of reinforced soil slope (RSS) system with a maximum slope of 65°. An embankment fill of average 70 m height with steep slopes located in high rainfall area is a unique feature of this project. The fill was reinforced with high-strength uniaxial geogrids laid perpendicular to the slope. Weld mesh wrapped with coir mat acted as facia units to protect it against surface failure. Considering high rainfall received on this table top airport site, extensive drainage system was designed for the high embankment fill. Gabion wall up to 9 m height were also designed and constructed along the boundary to accommodate the toe of the RSS fill beside the jeepable track at the base level. The design of RSS fill was done using ReSSA software and verified in PLAXIS 2D modeling. The site won excavated laterite soil was used as the fill material for the construction. Extensive field and laboratory tests were conducted during the construction of RSS system for quality assurance.
