A grillage foundation is essentially a:

(ಗಿ) Shallow foundation அதன்‌ Deep foundation

(C) Spread foundation (D) Pile foundation
Maximum bearing capacity can be expected from :

(A) Laminated rocks (B) Compact coarse sand

(C) Soft rocks (D) Granite rocks
The type of foundation suitable for under water structures is

(ಗ) Cast in situ concrete piles (B) Pier foundation

(C) Continuous footing (D) Stepped foundation

The most common sampler used for obtaining a disturbed sample of soil is :

(A) Split spoon sampler (B) Thin wall shelby tube sampler

(C) Open drive sampler (D) Piston sampler
The ultimate bearing capacity of a surface strip footing on clay, according to Terzaghi’s
theory is :

(A) 8.7൦ (0) 5.14 ९

© 4B (0) 96

Where ¢= unit cohesion, g,,= unconfined compressive strength, and B = width of footing

30. Negative skin friction on a pile under vertical compressive load acts :
(^) Downwards and increases the load carrying capacity of the pile
(B) Downwards and reduces the load carrying capacity of the pile
(C) Upwards and increases the load carrying capacity of the pile
(0) Downwards and maintains the same load carrying capacity of the pile

81. An ideal fluid is one which :
(൮) Obeys Newton's law of viscosity
(B) Flows through pipes with least friction
(C) ಓ frictionless and incompressible
(12) Satisfies continuity equation
32. For a fluid in motion, if pressure at a point is same in all directions, then 5 fluid is said
to be :
(^) Areal fluid (B) Anon Newtonian fluid
(C) An ideal fluid (0) A Newtonian fluid
