- Soil-water characteristic curve (SIVEC) for unsaturated soils
Advanced Testing
Using advanced technology capable of performing specific loading patterns including cyclic loading.
- Direct shear machines specifically designed to perform pipe-soil interaction (PSI) testing, constant normal load (CNL) constant normal displacement (CNH) and constant stiffness (CNS) test conditions
- Tilt table for interface testing at low stress conditions
- Static consolidated isotropic / anisotropic undrained / drained (CIU / CAU / CID / CAD) triaxial
- Dynamic CIU / CAU / CID / CAD triaxial
- Static CIU / CAU / CID / CAD
simple shear - Dynamic CIU / CAU / CID / CAD simple shear
- Small strain stiffness measurement using Bender Elements
- Maximum shear modulus (Gmax), shear modulus degradation and damping ratio measurement using resonant column and torsional shear modulus
Model Testing
Model testing can be accommodated in the GTI Perth warehouse with a footprint of 266m2. We are experienced in setting up large model tests to simulate near real situation conditions for projects.
GTI Perth mini T‑bar system (MTS) was developed in-house and can be purchased or hired for testing in box core samples or similar sample sizes and can achieve penetration up
to 750 mm below sample surface. Both static and cyclic loading can
be performed with the GTI Perth MTS unit.
Geotechnical Site Characterisation
From planning to reporting of geotechnical scope of work:
- Liaise with project team and collect all available data from site
- Explore all relevant databases
- Ensure that work is performed as per specification and to the highest standard
Data Interpretation and Integration
Interpretation of field and laboratory data to derive engineering parameters required for the design of proposed structures.
Research & Development
Continuous development and improvement of equipment and software using latest technology in data acquisition and control.
Non-destructive Testing
GTI Perth is working closely with Geotek to offer scanning of core samples using a self-contained laboratory. Testing can be done
at GTI Perth facility or on site
and include:
- X-ray Computing Tomography (XCT): Imaging of core samples while samples remain inside their liners or sampling tubes. Linear scan images or 3-D images can be generated using this system or Computerised Tomography of samples (CT Scan)
- High quality core photography scan
- Geohazard core logging including splitting of core liners, preparation of core surface, detailed sedimentology and geological logging
- Multi-sensor Core Logger (MSCL): Core samples scanned at set intervals across various types of sensors to determine physical properties of cores. This system, housed at GTI Perth, can provide:
- Gamma density
- P-wave velocity
- Magnetic susceptibility
- Resistivity
- X-ray fluorescence (XRF)
Sample Management and Storage
- Administer a register of samples, updated as required and provided to client upon request
- Provide ambient storage within GTI Perth warehouse
- Provide controlled temperature and humidity storage in bespoke modified 20ft sea container, with continuous monitoring by data loggers
