Part 1: Geotechnical Engineering—A Historical Perspective (Questions 1–25)
1. Which of the following individuals is widely considered the “father” of modern soil mechanics?
A. Charles-Augustin de Coulomb
B. Karl Terzaghi
C. Henri Darcy
D. Arthur Casagrande
Answer: B
Explanation: Karl Terzaghi’s pioneering work in soil mechanics and foundation engineering earned him
the title “father of modern soil mechanics.”
2. Which ancient civilization is credited with one of the earliest uses of geotechnical principles in
constructing canals and flood control systems?
A. Romans
B. Greeks
C. Egyptians
D. Babylonians
Answer: D
Explanation: The Babylonians constructed extensive canal systems for irrigation and flood control,
demonstrating early understanding of soil and foundation behavior.
3. Coulomb’s contribution to geotechnical engineering is most notably related to:
A. Effective stress principle
B. Consolidation theory
C. Shear strength of soils
D. Liquefaction phenomenon
Answer: C
Explanation: Charles-Augustin de Coulomb’s work on shear strength and earth pressure theory laid
important groundwork for soil mechanics.
4. Karl Terzaghi’s concept of effective stress states that:
A. Soil particles are weightless in water
B. The total stress equals the sum of pore-water pressure and effective stress
C. Soil friction angle remains constant in all water conditions
D. Water does not affect soil shear strength
Answer: B
PAGE 1
, Explanation: Terzaghi’s effective stress principle explains how total stress in a saturated soil is
distributed between pore-water pressure and the intergranular contact stress (effective stress).
5. Which of the following major infrastructure failures helped catalyze the modern field of soil
mechanics?
A. The Leaning Tower of Pisa
B. The collapse of the Tacoma Narrows Bridge
C. The failure of the St. Francis Dam
D. The failure of the Teton Dam
Answer: A
Explanation: The Leaning Tower of Pisa (started in 1173) highlighted differential settlement issues in
foundation engineering, prompting future investigations into soil-bearing capacity.
6. Which engineer introduced the concept of the hydraulic gradient for water flow in soils?
A. Joseph Valentin Boussinesq
B. Henri Darcy
C. G.G. Stokes
D. Atterberg
Answer: B
Explanation: Henri Darcy introduced Darcy’s Law, which is fundamental to understanding water flow
through porous media.
7. What was the primary focus of Arthur Casagrande’s research in soil mechanics?
A. Consolidation and settlement
B. Effective stress principle
C. Atterberg limits and soil classification
D. Pile foundation design
Answer: C
Explanation: Arthur Casagrande refined Atterberg’s plasticity limit tests and soil classification methods.
8. In the 18th and 19th centuries, much of the knowledge of soil behavior was derived from:
A. Rigorous laboratory testing
B. Numerical modeling
C. Empirical observations and field experiences
D. Government regulations
Answer: C
Explanation: Before modern soil mechanics theory, engineers relied heavily on practical observations
from trial-and-error construction practices.
9. Which statement best describes early geotechnical engineering approaches?
A. Purely theoretical analyses
B. Reliance on standardized laboratory methods
C. Heavy use of digital simulations
D. Empirical design rules based on observed failures and successes
Answer: D
Explanation: Early geotechnical methods were primarily empirical, based on observed successes and
failures in the field.

, 10. Which engineer’s work on consolidation theory is considered groundbreaking for predicting
settlement of clay soils?
A. L. Terzaghi
B. J. Boussinesq
C. Karl Terzaghi
D. A. Atterberg
Answer: C
Explanation: Karl Terzaghi’s one-dimensional consolidation theory remains the basis for predicting
settlement in saturated clay soils.
11. The development of soil mechanics accelerated in the early 20th century due to:
A. Increased laboratory testing and theoretical frameworks
B. Complete absence of major construction failures
C. Decreased need for large infrastructure projects
D. Ban on empirical construction methods
Answer: A
Explanation: The rapid growth of railroads, dams, and large buildings in the early 20th century spurred
the need for systematic studies of soil behavior, prompting laboratory testing and analytical methods.
12. Which of the following texts by Karl Terzaghi is considered one of the earliest comprehensive
works on soil mechanics?
A. “The Mechanics of Soils”
B. “Erdbaumechanik auf Bodenphysikalischer Grundlage”
C. “Foundations of Earth”
D. “Soil Classification for Engineers”
Answer: B
Explanation: Terzaghi’s 1925 book, “Erdbaumechanik auf Bodenphysikalischer Grundlage,” was a
groundbreaking treatise on soil mechanics.
13. Karl Terzaghi’s effective stress principle fundamentally changed geotechnical engineering by:
A. Eliminating the need for site investigation
B. Showing that pore water pressure does not influence soil strength
C. Demonstrating how water pressure and particle contact pressure govern soil behavior
D. Stating that soil strength is independent of loading rate
Answer: C
Explanation: Terzaghi’s principle showed that total stress in soil is split between pore water pressure
and particle contact (effective) stress, crucial for understanding shear strength and settlement.
14. Early earthwork constructions such as city walls and moats depended on geotechnical principles
related to:
A. Effective stress analysis
B. Ground improvement and slope stability
C. Soil compaction control using heavy machinery
D. Reinforced earth structures
Answer: B
Explanation: Early civilizations accounted for slope stability, seepage barriers, and ground improvement
(often by manual methods) for protective structures.
