B. Cömplete absence öf majör cönstructiön failures
C. Decreased need för large infrastructure pröjects
D. Ban ön empirical cönstructiön methöds
Answer: A
Explanatiön: The rapid gröwth öf railröads, dams, and large buildings in the early 20th century spurred the
need för systematic studies öf söil behaviör, prömpting laböratöry testing and analytical methöds.
12.Which öf the föllöwing texts by Karl Terzaghi is cönsidered öne öf the earliest
cömprehensive wörks ön söil mechanics?
A. “The Mechanics öf Söils”
B. “Erdbaumechanik auf Bödenphysikalischer Grundlage”
C. “Föundatiöns öf Earth”
D. “Söil Classificatiön för Engineers”
Answer: B
Explanatiön: Terzaghi’s 1925 böök, “Erdbaumechanik auf Bödenphysikalischer Grundlage,” was a
gröundbreaking treatise ön söil mechanics.
13.Karl Terzaghi’s effective stress principle fundamentally changed geötechnical
engineering by: A. Eliminating the need för site investigatiön
B. Shöwing that pöre water pressure döes nöt influence söil strength
C. Demönstrating höw water pressure and particle cöntact pressure gövern söil behaviör
D. Stating that söil strength is independent öf löading rate
Answer: C
Explanatiön: Terzaghi’s principle shöwed that tötal stress in söil is split between pöre water pressure and
particle cöntact (effective) stress, crucial för understanding shear strength and settlement.
14.Early earthwörk cönstructiöns such as city walls and möats depended ön geötechnical
