Engineering Geology

Geology is the science concerned with the Earth

and the rocks of which it is composed, the

processes by which they were formed during

geological time, and the modelling of the Earth's

surface in the past and at the present day.

8

Engineering Geology

Geologists• Study problems• Qualitative analysis emphasized (traditionally)• See earth as complex (heterogeneous & anisotropic)

Engineers• Solve problems• Quantitative analysis emphasized• Models often simplified/simplistic

Engineering Geology

Engineering geology is the application of geological data, techniques and principles to the study of rock and soil surficial materials, and ground water. This is essential for the proper location, planning, design, construction, operation and maintenance of engineering structures. Engineering geology complements environmental geology, or hydrogeology

Engineering Geology

Why Engineering Geology matter?

•Serve civil engineering to provide information in 3 most important areas:

1–Resources for construction;

•Aggregates, fills and borrows.

2–Finding stable foundations;

•Present is the key to the past –geology

•Past is the key to the future -engineering

3–Mitigation of geological hazards

•Identify problems, evaluate the costs, provide information to mitigate the problem

Engineering Geology

Importance of engineering geology to in Civil engineering

1.The investigation of foundations for all types of major structures, (dams, bridges, airports, large buildings, and towers.)

2.The evaluation of geologic conditions along tunnel,

pipeline, canal, railway, and highway routes. 3.The exploration and development of sources of rock,

soil and sediment for use as construction material.

4.The investigation and development of surface and

groundwater resources.

Importance of engineering geology to in Civil engineering practices

5.The evaluation of geologic hazards such as landslides, faults and earthquakes, radon, asbestos, subsidence, expansive and collapsible soils, expansive bedrock, cavernous rock, and liquefaction.

6.Evaluation of geologic conditions (including groundwater) affecting residential, commercial, and industrial land use and development.

7.Construction geology, including slope stability, dewatering, sub-drains, grouting considerations, and excavatability.

8.Safe siting and geologic design considerations for waste management and disposal facilities and to in establishing the bases for remedial actions for mitigation of related environmental threats from un-engineered and

uncontrolled waste disposal 13

Engineering Geology

The Engineering Geology was established in US after the St. Francis Dam near Los Angeles, CA failed on March 12, 1928. Engineering community realized the importance of Geology factor in civil engineering

Engineering Geology

1, Highway alignment, locations of right-of-way for the proposed construction;

2, Subsurface exploration along highway centerline and bridge foundations;

3, Classification of materials for excavation, rock versus common borrow (soil);

4, Cut and fill volumes determined to minimize the need of offsite borrow pits or rock waste areas; volume changes in both soil and rock from the cut to the fill are estimated;

5, Recommend angle of back slope (rock cut slope) based on rock conditions;

6, Groundwater aspects related to construction;

7, Evaluation of landslide-prone areas;

8, Recognition of compressible soil materials;

9, Construction materials, location and inventory;

10, highway effects on adjacent landowners;16
