Question

The name of a person in Column 1 is to be matched with the test mentioned in Column 2.

Column 1	Column 2
(I) Menard	(P) Dilatometer test
(II) Marchetti	(Q) Pressuremeter test
(III) Casagrande	(R) Compaction test
(IV) Proctor	(S) Liquid limit test

Option giving the CORRECT match between Column 1 and Column 2 is:

• A. (I) - (Q) ; (II) - (P) ; (III) - (S) ; (IV) - (R)
• B. (I) - (R) ; (II) - (S) ; (III) - (Q) ; (IV) - (P)
• C. (I) - (P) ; (II) - (Q) ; (III) - (S) ; (IV) - (R)
• D. (I) - (R) ; (II) - (S) ; (III) - (P) ; (IV) - (Q)

Hint:

Recall which geotechnical engineer each in-situ or lab test is named after: Menard (pressuremeter), Marchetti (dilatometer), Casagrande (liquid limit), Proctor (compaction).

Answer 1

The Correct Option is A

This question tests whether you know which in-situ or laboratory test each named engineer or geotechnical pioneer is associated with. Go through each name in Column 1 and match it with the test it is known for.

1. (I) Menard: Louis Menard developed the Menard pressuremeter, an in-situ test where a cylindrical probe is expanded radially inside a borehole to measure the stress-strain response of the surrounding soil. So Menard matches with (Q) Pressuremeter test.
2. (II) Marchetti: Silvano Marchetti developed the flat plate dilatometer test (DMT), where a flat blade with an expandable steel membrane is pushed into the ground to estimate soil properties from membrane expansion pressures. So Marchetti matches with (P) Dilatometer test.
3. (III) Casagrande: Arthur Casagrande designed the standard liquid limit device (the Casagrande cup and grooving tool apparatus), used to find the liquid limit of fine-grained soils by counting the blows needed to close a groove in a soil pat. So Casagrande matches with (S) Liquid limit test.
4. (IV) Proctor: Ralph Proctor developed the standard compaction test (Proctor test), which finds the relationship between moulding water content and dry unit weight of compacted soil. So Proctor matches with (R) Compaction test.

Putting these four matches together: (I) - (Q), (II) - (P), (III) - (S), (IV) - (R), which is exactly option (A).

Let's summarize:

• Menard: pressuremeter test.
• Marchetti: dilatometer test.
• Casagrande: liquid limit test.
• Proctor: compaction test.

So the correct match is option (A): (I) - (Q); (II) - (P); (III) - (S); (IV) - (R).
