HEAD of LABORATORY 
Dr. AHMAD RIFA’I

The main activity of this laboratory is to serve the education, research and development and public services as the primary goal. Soil Mechanics Laboratory at the forefront leading the field of Geotechnical Engineering that has an important role in the design, construction, maintenance and forensic engineering.

Soil Mechanics Laboratory has various facilities, consists of laboratory testing, in-situ testing, numerical modelling and expert reports related to Geotechnical Engineering.

Services

Soil Mechanics Laboratory has researched several programs, such as:

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