4. ENGINEERING GEOLOGY
     - Map of load bearing capacity of soil base
  •      - Engineering geological actual material map
  •      - Map of engineering geological borehole logs
  •      - Maps of urban geological investigation, maps of environmental geological investigation
  • 2. Soil investigation for various civil engineering

         - Geotechnical exploratory drilling up to 100m deep onshore and offshore.

          - Standard penetration test and static cone penetration test.

          - Vane shear test.

         - Static plate load test and collapse load test in pit.

    3. Soil treatment

         - Excavation dewatering.

         - Sand pile and prefabricated vertical drains with preloading.

         - Pour pile and sonic test on pour piles.

    4. Thematic studies

         - Application of informatics technology in management and exploitation of engineering geological data.

         Monitoring for horizontal deformation.

         - Monitoring for pore pressure.

         - Investigation, monitoring and determination of generation mechanism, driving forces and trigger factors causing landslides on slopes.

    5. Special software 

    a) Geo- Slope Office V.5

         - GEO-SLOPE OFFICE V.5 is a product of GEOSLOPE International –Canada. GEO-SLOPE OFFICE V.5 includes 6 packages:

         - SEEP/W is a finite element software, used for modeling movement of water and distribution of pore pressure in porous media.

         - SIGMA/W is a finite element software, used for analyzing stress-strain in soil and rock media, from simple linear deformation to complex non-linear effective stress elastic-plastic deformation.

         - SLOPE/W is a finite element software, used for analyzing slope stability of a saturated and unsaturated soil and rock slope. SLOPE/W has application in the analysis and design for geotechnical, civil, and mining engineering projects.

         - QUAKE/W is a geotechnical finite element software product for the dynamic analysis of earth structures subjected to earthquake shaking. It can also be used to compute the excess pore-water pressures that may be generated. Once the QUAKE/W analysis is complete, the resulting stresses and pore-water pressures can then be used in SLOPE/W to analyze the stability aspects of the problem.

         - CTRAN/W is a finite element software product that can be used to model the movement of contaminants through porous materials such as soil and rock. The comprehensive formulation of CTRAN/W makes it possible to analyze problems varying from simple particle tracking in response to the movement of water, to complex processes involving diffusion, dispersion, adsorption


    b) Plaxis V. 7.2 

         -  Plaxis is a  finite element package specifically intended for the analysis of deformation and stability in geotechnical engineering projects.

        - Geotechnical applications require advanced constitutive models for the simulation of the non-linear and time-dependent behavior of soils.

         - Since soil is a multi-phase material, special procedures are required to deal with hydrostatic and non-hydrostatic pore pressures in the soil.

         - Plaxis is equipped with special features to deal with the numerous aspects of complex geotechnical structures.


    c) RockWork 

         - Management of borehole data and input of geophisic, chemical, lithological, stratigraphical, water level, fracture and borehole parameters.

         - Display various types of boring logs, stratigraphy, cross sections, fence sections and block schemes.

         - Contains series of geological facilities for generating maps of isolines, mesh, block schemes, calculating volumes, hydrogeological and geochemical facilities...
