sheet piles
sheets of interlocking steel or timber driven into the ground, forming a continuous sheet
SHEET PILES
resist lateral earth pressures
SHEET PILES
for transferring building loads to the underlying ground: mostly for firm soils or light loads
SHALLOW FOUNDATION
the branch of civil engineering that deals with [], [], and [], and their relation to the design construction and operation of engineering projects ([], [])

* Stability of natural and proposed earth slope
* Geotechnical Earthquake Engineering
excavations, grading, or filling
for transferring building loads to the underlying ground; mostly for weak soils or heavy loads
DEEP FOUNDATION
using geofabrics to [] the soil
strengthen
provide analysis and mapping of technical results obtained from seismic surveys, and
investigate subsurface conditions and materials to determine their properties and risks
GEOTECHNICAL OR GEOLOGICAL ENGINEERS (GENERAL)
Retaining Structure Systems:
Reinforced Earth Walls, Gavions, Tie-backs, Excavation Support Systems,
Clay is more [] because it can be [] however gravel and sand is [] and tend to have [] which can water seep through
okay, compressed, hard, gaps,
Designing of Shallow Foundations Systems – Bearing Capacity Failure - Transcona Grain Elevator
FOUNDATION SYSTEM
A typical geotechnical engineering
project begins with a [] of project needs to [] the required []. Then follows a [] of soil, rock, fault distribution and bedrock properties on and below an area of interest to determine their [] including how they
will interact with, on or in a proposed construction. Site investigations are
needed to gain an understanding of the [] in or on which the engineering will take place. Investigations can include the assessment of the risk to [], [] and the
[] from natural hazards such as earthquakes, landslides, sinkholes, soil
liquefaction, debris flows and rockfalls.

COMMON GEOTECHNICAL PRACTICE IN A PROJECT
Construction site - Soil samples, Lab (testing), soil properties, Design Office (design analysis), Design details - Construction site
analyze the relationship between physical structures and marine geology, anchoring systems, sediment erosion, slope stability, and foundations for offshore and coastal structures
GEOMECHANICS ENGINEER (MARINE OPERATIONS)
The [] practice begins with []
CE, GE
Geotechnical application:
tunneling
provide design and analysis of ponds containing discarded oil sands materials, water extraction from soil and sand, and steam injection into wells; and evaluate underground water layers
trapped in rocks (aquifers). They also provide advice on environmental restoration.
HYDROGEOLOGICAL ENGINEER
used in temporary works
SHEET PILES
design open pit walls, mine waste dumps and dam structures used in oil sands mining, and analyze slope stability, seepage and hydraulic separation on dam structures
GEOTECHNICAL OR GEOLOGICAL ENGINEERS (OIL SANDS
PROJECTS)
analyze the strength of soils, drill hole stability, stress constraint, permeability of rock formations and the degree of trapped hydrocarbons in underground reservoirs
RESERVOIR GEOMECHANICS ENGINEER (OIL & GAS OPERATIONS)
a discipline that applies the principles of engineering mechanics to soils to
predict the mechanical behavior of soil.
SOIL MECHANICS
Prevent soils from spreading laterally
RETAINING WALLS
soil to soil
retaining wall
Geotechnical Solutions:
GROUND IMPROVEMENT
used for reinforcement, separation, filtration and drainage in roads, retaining walls, embankments
GEO-FABRICS
differential settlement
SHALLOW FOUNDATION
