Active Rock Anchors
Product Description
Active Rock Anchors
Advanced Prestressed Ground Anchoring Solutions for Critical Infrastructure
Active Rock Anchors are high-capacity prestressed anchoring systems engineered to stabilize rock formations and ground structures by introducing controlled prestressing forces into the structural and surrounding ground mass. These advanced anchoring systems are extensively used in infrastructure, geotechnical, transportation, marine, and hydropower projects where structural stability, deformation control, and long-term load resistance are essential.
Designed for demanding site conditions, Active Rock Anchors provide immediate stabilization, controlled force transfer, and enhanced structural reliability for complex infrastructure and ground stabilization projects.
What are Active Rock Anchors?
Active Rock Anchors, also known as Prestressed Ground Anchors or Ground Anchor Systems, are specialized anchoring systems consisting of high-strength steel tendons installed into competent rock formations or engineered ground conditions and stressed using calibrated hydraulic jacking systems.
Unlike passive anchoring systems, Active Rock Anchors are prestressed during installation to apply controlled stabilizing forces into the structure and surrounding ground mass. This process improves structural stability, minimizes displacement, controls deformation, and increases the overall factor of safety of the system.
Active Rock Anchor Systems are commonly used where structures are subjected to uplift forces, lateral earth pressures, overturning moments, hydrostatic pressures, or unstable geotechnical conditions.
Components of Active Rock Anchor Systems
Active Rock Anchoring systems are engineered using advanced prestressing technology and corrosion protection systems to ensure durability, performance, and long-term structural reliability.
Core Components
High-strength prestressing steel tendons
Anchor heads and bearing plates
Corrosion protection sheathing systems
Free length and bond length assemblies
Cementitious grouting systems
HDPE ducts and centralizers
Hydraulic stressing and lock-off systems
Wedges, couplers, and anchorage assemblies
All system components are selected and designed based on project-specific geotechnical conditions, structural loading requirements, and service-life expectations.
Active Rock Anchor Installation Methodology
The Active Rock Anchor installation process follows controlled geotechnical and prestressing procedures to ensure efficient load transfer, anchorage performance, and long-term structural stability.
Installation Process
Drilling boreholes into competent rock formations or engineered ground conditions
Installation of anchor tendons and corrosion protection systems
Grouting of the bond length zone for secure anchorage and load transfer
Prestressing using calibrated hydraulic jacking systems
Application of specified lock-off load
Proof testing, load verification, and quality inspection
Each Active Rock Anchor system is stressed, tested, and verified to achieve the required design performance, structural safety, and long-term reliability.
Advantages of Active Rock Anchors

Frequently Asked Questions (FAQs)
What are Active Rock Anchors?
Active Rock Anchors are prestressed anchoring systems used to stabilize structures, slopes, retaining systems, and ground formations by applying controlled stabilizing forces through tensioned steel tendons.
How do Active Rock Anchors work?
Active Rock Anchors work by transferring prestressing forces into the structure and surrounding ground mass using hydraulic stressing systems, improving stability and reducing structural movement.
What is the difference between Active and Passive Rock Anchors?
Active Rock Anchors are prestressed during installation and provide immediate stabilization, while Passive Rock Anchors resist loads only after structural movement occurs.
Where are Active Rock Anchors used?
Active Rock Anchors are widely used in bridges, dams, retaining walls, deep excavations, tunnels, slope stabilization systems, marine infrastructure, and hydropower projects.
Why are Active Rock Anchors important in geotechnical engineering?
Active Rock Anchors help improve structural stability, control deformation, resist uplift and lateral forces, and enhance the overall safety and performance of critical infrastructure projects.
