Bearing Capacity of Soil MCQ with answer and solution

Concept

Plate load test scope and shallow foundation suitability

Formula

q_f / q_p = B_f / B_p

Step-by-step solution

1. Statement (i) is correct: The plate load test is a standard field test using a rigid plate to determine ultimate bearing capacity and immediate settlement for shallow foundations. 2. Statement (ii) is incorrect: The plate load test evaluates shallow footing behavior over a shallow bulb of pressure and is not used for designing deep pile foundations; pile load tests are used for piles. 3. Therefore, only statement (i) is true. Answer: A

Explanation

The plate load test is an in-situ field load test conducted in a test pit to evaluate the ultimate bearing capacity and immediate settlement of shallow foundations. It cannot evaluate deep pile foundations or long-term consolidation settlements, nor is it suitable when high water table conditions compromise the shallow pit.

Why the other options are wrong

B) Incorrect because statement (ii) is false. C) Incorrect because plate load tests do not govern pile foundation design. D) Incorrect because statement (i) accurately defines the plate load test's objective.

Shortcut

Plate load test = Shallow foundations only; Pile load test = Pile foundations.

Common mistake

Assuming plate load test data directly designs deep pile foundations.
