Question

Dashed lines in the figures given below represent joints. Considering only the orientations of the joints and the slope face, which one of the following represents the most stable slope? 

• A. (A)
• B. (B)
• C. (C)
• D. (D)

Hint:

For maximum slope stability, joints should be oriented perpendicular to the slope face to resist sliding.

Answer 1

The Correct Option is B

Step 1: Understanding joint orientations and slope stability.
In terms of slope stability, a joint that is aligned parallel to the slope face is more prone to sliding and can cause instability. Conversely, joints that are oriented perpendicular to the slope face tend to stabilize the slope.

Step 2: Analyzing the options.
(A) Option A: The joint is oriented in a way that may promote sliding along the slope face, which is less stable.
(B) Option B: This is the correct answer. The joint orientation in this figure will provide maximum stability by preventing sliding.
(C) Option C: The joint orientation in this option is not optimal for stability.
(D) Option D: The joint orientation may lead to some instability in the slope.

Step 3: Conclusion.
The correct answer is (B), as the joint orientation provides the most stable slope configuration.
