Short description about laboratory

Unlike other Geotechnical Engineering laboratories, PPAU-IR-ITB deals with not only soil and foundation engineering problems, but also deals with wider research interest. The research activities at our laboratory are a multi-disciplinary research carried out by experts from Civil Engineering, Mining Engineering, and Geophysics Department. The research covers a wide range of geotechnical engineering problems, which are necessary to fulfill the need of stronger engineering capabilities to support the fast economic growth of the country. This includes numerical and experimental research in geotechnical engineering, rock mechanics, geotechnical earthquake engineering, and geophysical site characterization.

Besides research activities that are funded by the government, many of the research works carried out at the laboratory are joint research with industries and professional companies. These joint-research works show strong linkage between the industries and the PPAU-IR.

Research area/ Expertise Currently, the laboratory has eight major research areas as follow:

  • Advanced Soil Mechanics and Foundation Engineering
  • Soil Modeling and Computational Geotechnics
  • Soil Dynamics and Soil-Structure Interaction
  • Rock Mechanics
  • Geotechnical Earthquake Engineering
  • Geophysics and Seismicity
  • Soft Soil Engineering
  • Soil Improvement
Facilities The laboratory is supported by sufficient number of computers and standard to advanced equipment for field and laboratory testing of soils and rocks. Our main field and laboratory equipment is listed below:

No Equipment No Equipment
1 Consolidation 10 Cyclic Triaxial
2 Triaxial CD/CU/UU 11 Triaxial for Rock
3 Unconfined Compression 12 Shaking Table
4 Permeability 13 CPT 2.5 ton
5 Atterberg Limit 14 CPT 10 ton
6 Direct Shear 15 Pressuremeter

  • SEEP/W (Finite Element Program for Seepage Analysis)
  • STABLE, SLOPE/W (Software for Slope Stability Analysis)
  • PLAXIS 2-D and 3-D (General Static and Dynamic Finite Element program for soils, rocks, and soil-structure interaction problems)
  • NEPSSIP (Nonlinear Elasto-Plastic Soil-Structure Interaction Program)
  • gINT (Software and dataBase for subsurface exploration)
  • APILE1, APILE2, SHAFT for Windows, LPILE Plus, GROUP3, PG, PILEGP (Software package for pile and pile-group analysis)
  • GEOTEK (Software for geotechnical engineering analysis and design)
  • WEAP (Wave Equation Analysis Program for Pile Driving)
  • FAD (Foundation And Analysis) package.
  • EQRISK (Software for seismic risk analysis)
  • SHAKE91 (Software for earthquake wave propagation analysis
  • FLUSH (Software for 2-D earthquake wave propagation analysis)
