    Numerical Analysis of Geocell Retaining Wall for Slope Stabilization of Netravathi River Bank
    (Springer Science and Business Media Deutschland GmbH, 2025) Anjana, S.; Menon, V.; Kolathayar, S.
    Stability of slopes is a major concern when it comes to construction near hills, excavations, embankments and river banks. Geosynthetics and geotextiles have proven to be extremely efficient in slope stabilization and landslide protection, among which the use of geocells has been drastically increasing. It is made up of geogrid like materials that give it sufficient tensile strength. This paper focuses on the use of geocells to construct a retaining wall to support an existing backfill. The study area is located at a Netravathi River bank which belongs to a temple in South Mangalore city. The aim of the work is to prevent flooding of the temple during heavy rainfall and the erosion of banks. Numerical analyses have been carried out by Limit Equilibrium Method (LEM) using GEO5 software and Finite Element Method (FEM) using PLAXIS 2D software. The results of displacements and factor of safeties have been compared for both methods to determine if the proposed structure is stable. Geocell retaining wall has been developed in PLAXIS 2D using a soil geocell equivalent composite model due to the difficulties of modelling its actual honeycomb like structure. The structure gives sufficient safety for static as well as pseudo static condition for different water levels hence preventing further erosion of existing soil. The design provided for the present work gives a factor of safety of 1.69 in LEM analysis and 1.90 in FEM analysis for the rapid drawdown condition in a psuedo dynamic analysis. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

    Slope Stability Analyses and Design for a Telecommunication Tower Site in Kodagu—Limit Equilibrium and Finite Element Approach with Spatial Data Integration
    (Springer Science and Business Media Deutschland GmbH, 2025) Menon, V.; Anjana, S.; Kolathayar, S.
    This paper examines slope stability issues at the All-India Radio Telecommunication tower site in Kodagu, Coorg, Karnataka, India, where the hillock on which the tower stands has shown signs of instability after the monsoon of 2022. This study proposes reclamation strategies to mitigate future landslips in the region. A spatial analysis utilizing open-source Digital Elevation Models and Scoop3D software was performed to identify critical locations prone to landslips. The designs were assessed using the Limit Equilibrium method (LEM) and Finite Element method (FEM). Both static and pseudo-static conditions were considered in the analyses, with and without reinforcement, using the Limit Equilibrium Method and Finite Element Method. The proposed design aligns with the United Nations Sustainable Development Goals (SDGs) 9 and 11, demonstrating a significant increase in the Factor of Safety by more than 10%. The study recommends a geocell-based hybrid retaining system as a comprehensive solution to enhance slope stability and protect the site from future landslips. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2025.
