Geophysical survey of engineering structures

and natural objects

Almaty, 2014

Geophysical surveys

• In 2012, the Kazakhstan Agency of Applied Ecology

started using the non-destructive testing of engineering

structures and natural objects.

• Building structures, facilities, architectural complexes,

road surface pavements and groundwater can be

analysed without any damage caused to their surface

or internal structure.

• The principle of directional transmission of

electromagnetic waves and seismic signals to the

object and recording the echo reflected from them

underlies in the basis of the NDT method.

• The decrypting of received signal gives us the most

accurate characteristics of the object or area.

• The method allows to detect physical objects, aquifers,

voids, pipelines and infrastructure hidden inside the

ground and buildings, under asphalt and concrete

pavement.

• KAPE has a full range of diagnostic

systems and related software:

• Georadar system «MALA Geoscience»;

• Geoelectric multielectrode station

SCALA 48;

• Multichannel seismic acquisition system

Lakkolit XM-3.

Seismic engineering station Lakkolit XM-3.

Scope and objectives

Seismograms in processing

- Survey of geological condition of

construction sites as a part of

engineering survey;

- Hydrogeological survey (determining

ground water level);

- Survey of earth dams and dam slopes

(determining depression curve in dam

body and in channel slopes);

- Localization of anomalous zones (with

decompression, humidification

processes).

Survey of Geotechnical Condition of Site

and Determining Lithological Layers

This method is based on measuring specific electric resistance of different rock

formations. It allows to identify various layers, their thickness and then to draw a

map of bedrock foundation roof.

Analysis of hazardous geological processes

and mapping of geological structures

Based on the results of geoelectric

cross-sections processing, a detailed

geological cross-section image is

prepared where each layer thickness

can be seen.
