Definition of engineering geology:
• According to IAEG (International Association for Engineering Geology)
1. IAEG statutes, Arnould, 1970
The application of the earth sciences to engineering planning, construction, prospecting, testing and processing of related materials.
2. IAEG statutes, 1992
The science devoted to the investigation, study and solution of the engineering and environmental problems which may arise as a result of the interaction between geology and the works and development of measures for prevention or remediation of geological hazard.
Definition of Engineering Geology according to IAEG (1992)
⚫ Engineering geology, is defined by the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards.
⚫ It simply refers to the application of geological principles to engineering studies.
Scope of geology in civil engineering:
⚫ Mining engineering
⚫ Water Resource Engineering
⚫ Geomechanics
⚫ Land use planning
⚫ Environmental engineering
⚫ Earthquake Engineering
⚫ Oceanography
⚫ Hydrogeological study
⚫ Construction material engineering
⚫ Tunneling
⚫ Foundation engineering - assessment of soil conditions
⚫ Construction materials engineering - quality of stones, lime,
cement etc.
⚫ Infrastructure engineering - location of bridges, tunnels, rivers
meandering zones
⚫ Disaster mitigation - seismic resistant structural design, flood
control, river training, waterway of bridges
⚫ Land-use engineering - soil erosion control, natural drainage
⚫ Water Resources engineering - hydrogeology, source and quality
of aquifer and water, desilting of reservoirs and channels
⚫ Environmental engineering - ecological balance, solid waste
management by landfill
Objectives and importance of geology in civil engineering:
⚫ Geology provides systematic approach to complete the constructions' groundwork smoothly and complete the civil engineering without any complications
⚫ The value of geology in Civil Engineering has been recognized only comparatively
recent years.
⚫ Geology provides a systematic knowledge of construction material, its occurrence, composition, durability and other properties. Example of such construction materials is building stones, road metal, clay, limestones and laterite.
⚫ The knowledge of the geological work of natural agencies such as water, wind, ice and earthquakes helps in planning and carrying out major civil engineering works.
⚫ For example the knowledge of erosion, transportation and deposition helps greatly in solving the expensive problems of river control, coastal and harbour work and soil conservation.
⚫ Ground water is the water which occurs in the subsurface rocks.The knowledge about its quantity and depth of occurrence is required in connection with water supply, irrigation, excavation and many other civil engineering works.
⚫ The foundation problems of dams, bridges and buildings are directly concerned with the geology of the area where they are to be built. In these works drilling is commonly undertaken to explore the ground conditions. Geology helps greatly in interpreting the drilling data.
⚫ In tunneling, constructing roads, canals, docks and in determining the stability of cuts and slopes, the knowledge about the nature and structure of rocks is very necessary.
⚫ Before staring a major engineering project at a place, a detailed geological report which is accompanied by geological maps and sections, is prepared. Such a report helps in planning and constructing the projects.
⚫ The stability of civil engineering structure is considerably increased if the geological feature like faults, joints, bedding planes, folding solution channels etc in the rock beds are properly located and suitably treated.
Role and task of an engineering geologist
⚫ Consult geological maps and aerial photographs to advice on site selection.
⚫ Perform desk studies and assess site information sources prior to field investigations.
⚫ Assist with design of built structures, using specialized computer software and calculations.
⚫ Assess findings for construction engineers.
⚫ Collect data and produce engineering geological reports.
⚫ Oversee progress of specific contracts related to engineering geology.
⚫ Conduct engineering calculations.
⚫ Assist in preparation of construction plans, specifications and cost estimates including material
quantity calculations.
⚫ Provide construction oversight, documentation, interpretation of drawings and specifications and other support services.
⚫ Gather, analyze and publish field and laboratory data in geotechnical report.
⚫ Conduct field investigations as geological mapping, geotechnical drilling and sampling.
⚫ Conduct engineering analyzes including slope stability.
⚫ Report geotechnical recommendations integral to successful design, construction and
maintenance of roads, airports and other engineered structures.
⚫ Perform logging and sampling drill holes and trenches, geological and structural mapping, and
installation and observation of down-hole instrumentation.
⚫ Collect, analyze and interpret geotechnical data.
Scope, objective and it's importance in context of Nepal:
⚫ Nepal has diverse topography with Himalaya, hill and Terai which comprises of variable geology.
⚫ Tectonically active Himalaya range comprises of many unique landforms to be studied prior to construction.
⚫ Different dynamic earth processes like weathering, erosion, landslides, earthquake makes the study of geology in Nepal important before starting any design.
⚫ Lack of better understanding of geology of an area may result in design
failure.
⚫ For the identification of different hazards study of geology is important for
Nepal.
⚫ Geology assist in the preliminary phase of investigation so that the implementation phase of design works which has not yet been possible in Nepal.
⚫ Geological study is therefore essential to avoid disasters, accidents and for the long lasting construction.
