About Soil Mechanics Laboratory:
Soil Mechanics Laboratories are set up on a total area of 500 m2 including controlled temperature (70m2) and humidity rooms (19m2). Some of the equipment are connected to data loggers for automatic recording.
Available equipment for soil tests:
• Standard equipment for soil classification,
• Automatic proctor compaction and CBR machine
• A small shaking table to assess maximum density of granular soils
• 4 conventional triaxial testing units (Wykham Farrance and ELE) for testing soil samples up to 10 cm diameter,
• Automated triaxial testing unit (VJ Tech)
• 4 direct shear machines one with residual testing attachment
• 1 large direct shear setup (30x30cm specimen with clamps for geosynthetics),
• 16 regular, 2 heavy-duty, 1 unsaturated 1-D compression/consolidation testing machines,
• Laboratory vane shear apparatus,
• Unconfined compression test setup
• In-situ and laboratory wedge shear testing devices developed at METU.
• Pressure plate extractor
• Infiltration column with tensiometers
• Hanging column setup
• Hollow cylinder dynamic torsional shear
• Unsaturated triaxial test setup (axis translation suction control and volume change measurement),
• A shaking table with a laminar tank dimensions of 1 m by 1 m by 1.5 m, to study dynamic earth pressures under harmonic base motions. The shaking table system can perform uni-directional dynamic experiments with random motion excitation in a fully computer controlled manner with a maximum frequency of 5 – 7 Hz (depending on the payload, maximum 2 tonnes), an amplitude of ±300 mm and at a maximum acceleration of amax = 0.3g
• Rainfall intensity-controlled flume setup (2 m long)
• Scaled model testing tanks of various sizes upto 1m3
