1.3. Introduction (General Concepts)

Question 1

the resistance to shear stress in terms of the effective internal friction angle and effective cohesion

Answer 1

Soil Shear Strength

Question 2

developed the theory of consolidation for clays

Answer 2

Karl Terzaghi

Question 3

developed the analysis of saturated clay slopes with the assumption that the critical surface of sliding is the arc of a circle. He gave correct numerical solutions for the stability numbers of circular slip surfaces passing through the toe of a slope

Answer 3

Wolmar Fellenius (1876-1957)

Question 4

developed relationships for lateral pressure and resistance in clay as well as bearing capacity for shallow foundations in clay

Answer 4

Arthur Langley Bell (1874-1956)

Question 5

Known as the Father of Modern Soil Mechanics, he pioneered the development of soil mechanics and presided over the first ISSMFE conference at Harvard University, covering topics like effective stress, shear strength, and soil testing techniques.

Answer 5
