GROUND IMPROVEMENT
soil to water
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 ([], [])
soil, rock, underground water, Coduto 1998
in civil engineering, Gravel + Sand is []

SOIL IMPROVEMENT
GEOTECHNICAL CHALLENGES (GEOHAZARDS):
* [] of [] and [] [] slope
* Geotechnical Earthquake Engineering

SHALLOW FOUNDATION
GEOTECHNICAL CHALLENGES (GEOHAZARDS):
* Impact of [], [], or []
* 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.
