GEOTECH LESSON 1-2 Flashcards
They were formed y movement of soils from its original place by gravity
Colluvial Soils
They were formed by deposition in the seas.
Marine Soils
They are formed from sediments, animals, and plant materials that are deposited in water or on land on the earth’s surface and then subjected to pressures and heat.
Sedimentary Rocks
They are formed from magma emitted from volcanoes that have cooled and solidified.
Igneous Rocks
They are ground fracture
Faults
It is the horizontal separation of a layer or bedding plane.
Strike
It is the calcium sulphate formed under heat and pressure from sediments in ocean brine.
Gypsum
It is the mixture of sand,, silt, and clay that may contain organic material
Loam
It is a wind blown, uniform fine-grained soil.
Loess
They are clays that undergo large volume changes from cycles of wetting and drying.
Expansive Soils
They were formed by deposition of quite lakes.
Lacustrine Soils
It is clay and silt mixed with water into a viscous fluid.
Mud
Based in the Earth’s profile, what are the layers of the earth?
Crust
Mantle
Core
The oldest and most complex engineering material
Soil
Western civilizations credit the ___ for recognizing the importance of soils in the stability of structures.
Romans
Served during the reign of Emperor Augustus in the first century B.C., paid great attention to soil types (sand, gravel, etc.) and to design and construction of solid foundations.
Vitruvius
First person to use mechanics to solve soil problems.
Coulomb
The application of engineering mechanics to the solution of problems dealing with soils as foundation and a construction material.
Soil Mechanics
Two tenets of engineering design.
Stability and Economy
Uncemented aggregate of mineral grains and decayed organic matter (solid particles) along with the liquid and gas that occupy the empty spaces between the solid particles
Soil
Application of the principles of soil mechanics to practical problems.
Soil Engineering
Father of Soil Mechanics
Karl Terzaghi
The science and practice of the part of civil engineering that involves natural materials found close to the surface of the earth.
It includes the application of the fundamental principles of soil mechanics and rock mechanics to foundation design problems
Geotechnical Engineering
These are application of fundamental principles to foundation design problems.
Soil Mechanics
Rock Mechanics
