Geophysics Studies

The use of geophysical methods as cheap and rapid methods for subsurface identification in various road construction projects, tunnels, civil and urban structures, railways, power lines, dams, etc., has become increasingly popular in Afghanistan in recent decades.

Necessity of conducting geophysical studies on ongoing and exploited projects in the areas of location of pipes, underground cables, identification of potential landslides on mountain roads, determination of risk zones, groundwater level, identification of ground layers, faults, loose layers, water saturation points, seepage in reservoirs (oil and water) and dams, geological domain as well as archaeological studies.

Since the right way to do geophysical studies in a project greatly affects the success of that project, the need for sufficient experience and expertise in planning and all stages of geophysical studies is provided by the Geotechnical Pamir Service Company, which provides comprehensive geophysical information through underground geophysical studies. The subsurface layers are obtained as follows:


  1. Separation of different subsurface layers of roads, power lines, railway lines, location and dimensions of underground rocks and thickness and type of underground layers.
  2. Identification of geological structures such as faults (strike& slopes), folds, discontinuities, etc. To build large structures such as tunnels, dams, roads and etc.
  3. Comprehensive pre-geotechnical drilling information for complete and detailed identification of the study area and site to reduce the projected drilling area and ultimately reduce project costs.
  4.  Determine the amount of subsurface rock porosity and amount of settlement.
  5. Identify loose and hard areas beneath the surface to determine the structure of structures.
  6. Determine the Convenient location to build the bridge and install the foundations.
  7. Determination of loose underground formations and urban hazardous areas and risk areas; Seismic studies and determination of urban faults and areas with unfavorable bedding for construction.
  8. Exploration of underground aquifers to construct water wells for agricultural lands, factories, workshops and industrial settlements.
  9. Study the water passages and identify the looseness and stiffness of the walls and floors in the tunnel.
    1. Determine the corrosion rate of the underground gas and oil pipelines.
    2. Determination of salinity, sweetness and type of salts present in water.
    3. Determine the amount of earth's electrical resistance at the site of power stations construction.
    4.  Determination of landslide in areas with landslide potential.
    5. Determine the location of karst caves and cavities in the basement.
    6.  Provide the geometric shape of the aquifer.
    7. Identify contaminated areas such as underground oil and gas contamination due to bursting of gas and oil pipes and identify the location of bursting pipes for repair.
    8. Determine the weakness of the structures site and identify the weakest part of the structures bed to concentrate geotechnical operations in that area and reduce the geotechnical operations in other parts of the site.
    9. Determination of underground formation and subsidence and bedding levels, determination of corrosive textures of seismic studies and identification of hazardous sites on the study site.
    10. Studies of passages, tunnels, urban underpasses and the provision of a low cost water guidance plan to prevent passage congestion as well as protect the structure against water penetration.
    11. Identification of cavities, aquifers and anomalies and underground installations.
    12. Geophysical studies of the construction of important structures;
    13. Groundwater identification and separation of contaminated and high quality sources.

Directing the water involved to the permeable layers and reducing the effects of scour and flood hazards for the transmission lines, railways, passages and underpasses (as well as directing surplus water to the bottom layers and conserving these valuable resources.
