Askar Reclamation – Riprap Revetment Geotech Design Bahrain
Project Overview
GeoStruXer was approached by Alomara Engineering to design and evaluate the stability of a 2.75m high and 6m wide riprap revetment system spanning 500m for the Askar Reclamation Project in Bahrain. The work focused on geotechnical analysis, construction staging, and stability assessments to ensure robust and sustainable performance under various load and seepage conditions.
Challenges
Solution Approach
Advanced Modelling
Used PLAXIS 2D with a Mohr–Coulomb model to assess small displacements.
Optimised Design
Accounted for tidal (1.5m) and storm surge (0.5m) ranges, resulting in a 2.75m wall height.
Settlement & Stability
Evaluated settlement, stability, and seepage for each construction phase, ensuring safety.
Value Engineering & Sustainability
Material Efficiency
Simplified design and optimised material use.
Sustainability
Layered boulder placement and geotextile reduced environmental impact.
Cost-Effective
Eliminated overdesign while maintaining safety margins.
