Slope Protection Works for the Construction of Hasic - Ash Shuwaymiyah Road
Protecting a Critical Coastal-Mountain Road Through Engineered Slope Stabilization
The Hasic - Ash Shuwaymiyah Road traverses some of Oman's most challenging terrain, combining steep coastal cliffs, fractured rock faces, and long cut slopes exposed to weathering and erosion. Ensuring the safety and long-term performance of this strategic road required extensive and carefully engineered slope protection measures.
TEICO was engaged to deliver large-scale slope protection solutions capable of addressing both surface instability and high-energy rockfall hazards along the alignment.
Project Overview
The project involved slope protection works across extensive cut slopes created during road construction. These slopes presented varying rock conditions, from weathered surface layers to competent rock requiring high-energy interception systems.
The scope combined surface containment and rockfall protection to deliver a comprehensive stabilization strategy.
Project Details
- Project: Construction of Hasic - Ash Shuwaymiyah Road
- Client: Sultanate of Oman - Ministry of Transport & Communications
- Scope: Slope Protection
- Quantities Delivered:
- 145,000 m² Reinforced Wire Mesh
- 50,000 m² Simple Wire Mesh
- 26,250 m² Rockfall Barrier - 500 kJ
- 10,000 m² Rockfall Barrier - 1,000 kJ
Challenges Identified
- Extensive and Continuous Cut SlopesLong, uninterrupted slope faces increased the potential for progressive instability and rockfall propagation.
- Highly Variable Rock ConditionsThe alignment crossed weathered zones, fractured rock, and competent formations, each requiring different protection approaches.
- Exposure to Coastal and Mountain WeatherWind, rainfall, and temperature variations accelerated erosion and surface degradation.
- Risk of High-Energy Rockfall EventsSteep slope geometry created the potential for large rock blocks to gain significant energy before reaching the roadway.
Solution Implemented:
1. Surface Containment Using Wire Mesh Systems
- •Installed 145,000 m² of reinforced wire mesh to restrain loose material and stabilize weathered rock faces.
- •Applied 50,000 m² of simple wire mesh in areas with lower instability risk to provide cost-effective surface protection.
2. Rockfall Interception Systems
- •Installed 26,250 m² of 500 kJ rockfall barriers to intercept moderate-energy rockfall events along vulnerable sections.
- •Installed 10,000 m² of 1,000 kJ rockfall barriers in high-risk zones where greater impact resistance was required.
3. Integrated Protection Strategy
- •The combination of surface mesh and energy-rated barriers ensured both containment of loose material and interception of falling rocks before reaching the road.
Project Outcomes: Slope Protection Works for the Construction of Hasic - Ash Shuwaymiyah Road
Improved Stability Across Large-Scale Slopes
The extensive installation of mesh systems provided consistent surface confinement across long sections of cut slopes.
Effective Protection Against Rockfall Hazards
Energy-rated rockfall barriers significantly reduced the risk of rockfall impacts on the roadway.
Adaptable Solutions for Varying Ground Conditions
The use of multiple protection systems allowed tailored responses to changing slope conditions along the alignment.
Long-Term Safety for Road Users
The stabilized slopes now provide a safer driving environment along a critical transport link.
Durable and Sustainable Infrastructure
The engineered systems are designed for long service life with minimal intervention, supporting sustainable road operation.
