Design of a Geo-Grid Reinforced Soil Wall of Height 15m Using ReSSA Software

Abstract

As the highway construction in hilly areas progress, the 4 laning of exiting highway is proposed due increase in traffic. The side of the highway where a slope stabilisation or soil retaining is required for higher depths duet presence of vertical slopes, the various retaining structures such retaining wall and gabion wall can be constructed, but these are feasible and economical for smaller heights that is up to 7m or less. To further retain a soil various slope stabilisation techniques can be used. Geo-grid Reinforced soil wall is technique that requires use of geogrid and coir mat to construct a soil wall like structure to provide an area and stabilized road way for propagating traffic. This paper involves study and design of a Geo-Grid Reinforced Soil wall for site in Himachal Pradesh on project of Four laning of Kiratpur to Ner-Chowk of Section of NH 21 from km 73.000 to km 186.500 in States of Punjab and Himachal Pradesh with Project length of 84.380 km and 327.000 lane km
