Which is an example of cased cast-in-situ concrete pile?

Select the correct statement:

What does not fit into the classification of pile based on function?

Match the following

A) Electro-osmosis

B) Under reamed pile

C) Cellular cofferdam

D) Raft foundation

I. Provide water free area for work

II. Eliminate differential settlement

III. Dewatering of fine grained soil

IV. Foundation for expansive soil

A square pile group of 16 piles penetrates through a filled up soil of 3 m depth. The pile diameter is 250 mm and pile spacing is 0.75 m. The unit cohesion of the material is 18 kN/m² and the unit weight of soil is 15 kN/m³. What will be the negative skin friction for piles acting individually? (Assume reduction factor m = 0.4)

When the length of a pile is up to 34 times their least width, then the area of the steel should not be less than

The minimum centre to centre distance between friction piles of 1 m diameter, is:

The diameter of enlarged bore or bulb for under reamed piles used in expansive soils is generally taken as

For group action of piles minimum center spacing of end bearing piles is.
