31
Which geological structure is most dangerous for dam construction?
Discuss
Answer & Solution
Answer: Option C
Solution:
Faults are fractures along which movement has occurred.They may act as seepage paths and reduce foundation stability in dams.
32
What is the primary concern of constructing on expansive clay?
Discuss
Answer & Solution
Answer: Option C
Solution:
Expansive clays swell when wet and shrink when dry, causing structural damage through ground movement.
33
Which rock feature significantly affects its strength in a construction project?
Discuss
Answer & Solution
Answer: Option B
Solution:
Foliation is the planar arrangement of minerals in metamorphic rocks.It creates planes of weakness that reduce strength and stability.
34
What type of slope failure is most common in layered sedimentary rock?
Discuss
Answer & Solution
Answer: Option D
Solution:
Planar slides occur when bedding planes dip in the direction of the slope, enabling layers to slide.
35
Which type of rock is most suitable for heavy foundation loading?
Discuss
Answer & Solution
Answer: Option D
Solution:
Basalt is dense, strong, and has high compressive strength, making it suitable for heavy structures.
36
Which method is used to test the in-situ strength of rock mass?
Discuss
Answer & Solution
Answer: Option C
Solution:
Schmidt hammer is a non-destructive test for estimating surface hardness and strength of rock in the field.
37
What is a major issue with highly jointed rock masses?
Discuss
Answer & Solution
Answer: Option D
Solution:
Jointed rocks have discontinuities that reduce overall rock mass strength and compromise structural stability.
38
Why is rock permeability important in underground construction?
Discuss
Answer & Solution
Answer: Option B
Solution:
Permeability governs the rate of water inflow into tunnels or shafts, affecting dewatering and support design.
39
Which soil condition is most favorable for shallow foundations?
Discuss
Answer & Solution
Answer: Option D
Solution:
Dense sand offers high bearing capacity and low compressibility, making it ideal for shallow foundations.
40
Which geological feature may create water leakage in a dam foundation?
Discuss
Answer & Solution
Answer: Option B
Solution:
Faults are fractured zones that may serve as conduits for water, potentially causing leakage under dams.
