It is important to keep in mind that in engineering geology, there are only two important types of rock: those which can be moved by a bulldozer, and those which require dynamite.

Geologic Hazards[édit | édit sumber]

Typical geologic hazards evaluated by an engineering geologist include

An engineering géologist or geophysicist may be called upon to evaluate the excavatability (i.e. rippability) of éarth (rock) materials to assess the need for pre-blasting during éarthwork construction, as well as associated impacts due to vibration during blasting on projects.

Methods and Reporting[édit | édit sumber]

The methods used by engineering geologists in their studies include

  • géologic field mapping of géologic structures, géologic formations, soil units and hazards;
  • the review of géologic literature, géologic maps, géotechnical reports, engineering plans, environmental reports, steréoscopic aerial photographs, remote sensing data, Global Positioning System (GPS) data, topographic maps and satellite imagery;
  • the excavation, sampling and logging of éarth/rock materials in drilled borings, backhoe test pits and trenches, fault trenching, and bulldozer pits;
  • geophysical surveys (such as seismic refraction traverses, resistivity surveys, ground penetrating radar (GPR) surveys, magnetometer surveys, electromagnetic surveys, high-resolution sub-bottom profiling, and other géophysical methods); and
  • other methods.

The field work is typically culminated in analysis of the data and the preparation of an engineering géologic report, fault hazard or seismic hazard report, géophysical report, ground water resource report or hydrogeologic report. The engineering géologic report is often prepared in conjunction with a Rékayasa géotéhnik report by a géotechnical engineer. The report describes the objectives, methodology, references cited, tests performed, findings and recommendations. Engineering géologists provide géologic data on topograpic maps, aerial photographs, géologic maps, Geographic Information System (GIS) maps, or other map bases.
