Study Notes
Introduction to Geotechnical Engineering
- Geotechnical engineering is a branch of civil engineering focused on the behavior of earth materials (soil and rock).
- It applies principles and methods of soil and rock mechanics to solve engineering problems and design projects.
Soil Mechanics
- Soil mechanics is a branch of engineering science focusing on the properties and behavior of soil as a structural material.
- The goal of studying soil mechanics is to establish principles, theories, and procedures for creating safe and sound structures.
- Foundation engineers need to interpret soil mechanics principles to adjust projects to site conditions.
History of Soil Mechanics
- In 1930, Karl Terzaghi established soil mechanics as a civil engineering branch.
- Terzaghi's contributions were significant, and he is known as the "Father of Soil Mechanics".
Preclassical Period (1709-1776)
- Studies focused on natural slopes and unit weights of various soil types.
- Semi-empirical earth pressure theories were developed.
Classical Period - Phase I (1776-1856)
- French scientists, like Charles Augustin Coulomb, used calculus to study retaining walls.
- Gaspard Clair Marie Riche de Prony included Coulomb's theory in his textbook.
Classical Period - Phase II (1856-1910)
- Jean Victor Poncelet expanded Coulomb's theory with a graphical method for lateral earth pressure.
- Alexandre Collin provided details for deep slips in slopes and embankments.
- Henri Philibert Gaspard Darcy studied sand filter permeability, and other notable contributions were made by Sir George Howard Darwin and Joseph Valentin Boussinesq.
Modern Period (1910-1927)
- Albert Mauritz Atterberg explained the consistency of cohesive soils through liquid, plastic, and shrinkage limits.
- Wolmar Fellenius developed stability analysis for saturated clay.
- Karl Terzaghi developed the theory of consolidation for clays.
Importance of Soil Mechanics
- Structures rely on soil to carry loads.
- Foundation types (shallow or deep) depend on soil strength.
- Dams, embankments, and roadways require soil analysis for successful construction.
Notable Structures in Ilocos Norte
- Paaoy Church, Bangui Windmills, Patapat Viaduct, Laoag International Airport, Cape Bojeador Lighthouse, Burgos Wind Farm, Crobaric Bell Tower, Sinking Bell Tower, Museo Ilocos Norte are examples of structures embodying geotechnical engineering principles.
Overall Significance of Geotechnical Engineering
- Geotechnical engineering plays a vital role in improving society by enhancing the durability of civil engineering structures.
