Soil Mechanical Laboratory

The main activities of the laboratory are to serve education, research & development and public services as its main purposes. The Soil Mechanics Laboratory leads in the forefront of Geotechnical Engineering field which has an important role in design, construction, maintenance and forensic engineering.
The Soil Mechanic Laboratory has various facilities, consisting of laboratory test, in-situ test, numerical modelling and experts’ reports related to Geotechnical Engineering.

Soil Mechanics Laboratory has been conducted several researches program, such as:

  1. Utilization coal ash as recycling material options in view point of geo-environment.
  2. Karst Material characterization & construction of underground river barrage.
  3. Local genius and rehabilitation of Prambanan temple due to earthquake.
  4. Characterization and constitutive model development of unsaturated soils in geotechnical engineering analysis and design.
  5. Slope stability analysis using numerical simulations including dynamic analysis.
  6. Soil reinforcement uses conventional and modern methods.
  7. Stress-deformation analysis using numerical simulations.
  8. 3D landslide numerical simulation: case studies.
  9. Study and development of foundation system on soft soil.
