Study Notes

Engineering Geology Overview

  • Engineering Geology is the application of geological data, techniques, and principles to study rocks, soil, surficial materials, and groundwater.
  • This is crucial for proper location, design, construction, operation, and maintenance of engineering structures.
  • It complements environmental geology.

Key Concepts of Engineering Geology

  • Geology encompasses the study of the Earth and its systems, including the materials and processes of the Earth and the origin and evolution of the planet through time.
  • Physical geology examines the materials and processes of the Earth.
  • Historical geology studies the origin and evolution of our planet.
  • The subject of Geology is divided into branches including Geophysics, Petrology, Mineralogy, Stratigraphy, Paleontology, Structural Geology, and Economic Geology.
  • Seismology studies the distribution and causes of earthquakes.
  • Engineering Geology applies geological knowledge to civil and mining engineering.
  • Geological factors influence civil and mining operations.
  • Engineering Geology identifies geological factors influencing planning, design, construction, and maintenance of engineering works.
  • Understanding geological hazards, like earthquakes, landslides, and floods, is part of engineering geology.
  • Geological data is important for finding safe locations for construction, stable foundations, and mitigating potential hazards.
  • Engineering Geology deals with rock, soil, water, their interactions, and their interactions with engineering materials and structures.
  • The different layers of the Earth (crust, mantle, core) are considered, plus their properties.

Preparation for the Course

  • Attend all classes.
  • Read both the textbook and the lab manual. Do this before each class.
  • Complete assigned homework.
  • Study hard for exams.
