Geotechnical Testing and Monitoring
Continuous Pile Monitoring
Continuous pile monitoring can be done by PDA test.
Pile Set Monitoring
Pile set monitoring can be done by Non Contact Deflection Tester.
Instrumented Pile Load Tests
Fibre Optic Strain Sensing Technology can be applied to instrumented pile load tests, providing continuous strain profiles throughout the pile during the load test. This offers detailed insights into the test pile’s capacity and performance.
The fiber optic system can be installed in various types of piles, including:
- Bored Pile
- Spun Pile
- RC Pile
- Micropile
- Steel Pipe Pile
- Caisson Pile
The Fibre Optic system is compatible with conventional Maintain Load Tests (Kentledge or Reaction Systems), as well as Bi-Directional Static Load Tests and Lateral Load Tests, providing precise measurement and analysis of pile performance under varying load conditions
Pile Raft Monitoring
Long term integrity monitoring of pile raft foundation using strain and temperature optical based sensor.
Instrumented Soil Nail & Rock Bolt Pull Out Test
- Instrumented Pull Out Test.
- Long Term Slope Monitoring
Road
Dynamic monitoring for the displacement of road performance assessment subjected to traffic load. Distributed Fibre Optic Strain Sensing Sensor and Fibre Bragg Grating Sensor can be used to monitor:
- Magnitude of load or pressure transferred down to subgrade
- Vertical land subsidence and influence depth below the road
- Long term road performance
Airport Runway
A series of Fibre Bragg Grating Sensor can be installed in the boreholes to identify changes in different subgrade layers of borehole. Hence, dynamic monitoring for the airport performance assessment subjected to traffic load can be obtained.
- FBG Extensometer to monitor displacement of the subgrade
- FBG Piezometer to monitor water pressure
- Long term airport runway performance
