Principles of engineering geology

Question 1

geology

Answer 1

• study of the solid and liquid matter that composes the earth
• includes composition, structure, physical properties, dynamics, and history of earths materials and the processes they go through
• important for mineral/hydrocarbon extraction, mitigation of natural hazards, and historical analysis

Question 2

Principles of Geology

Answer 2

• sir charles lyell

- the present is the key to the past

Question 3

Shen Kua

Answer 3

-formed hypothesis for land formation: land was formed by erosion of the mountains and by deposition of silt

Question 4

engineering geology

Answer 4

• provides link between geo and engineering through the formation of geological models
• models are used to identify geo hazards/uncertainty, plan effective ground investigations, and define ground blocks/geo structures to facilitate geotechnical risk assessment/design
• also concerned with the determination of geo and hydro conditions
• principles: an attempt to predict the future changes of the engineered earth’s surface by reference to causes now in operation

Question 5

reasons for geo engineering

Answer 5

• anticipating unforeseen ground conditions and making them become foreseen
• ground=geotechnically complex
• the complexity is not random/unpredictable
• geo engineering can anticipate this

Question 6

unforeseen ground conditions

Answer 6

ground conditions that were not understood 100% at deisgn stage and caused problems later on

Question 7

Applications of geo engineering

Answer 7

-for res, commercial, and indust…… anything to do with ground research
-in HK: terrain hazard assessment/mitigation
site formation
slope engineering
foundations
deep excavation
tunnels and caverns
marine works/reclamation
ladfills/contaminated land
nat resource assessment
