Question

Statement (I): Saturated fine, as well as medium, sands of uniform particle size are most susceptible to liquefaction.
Statement (II): Fine particles reduce the permeability which is a prime factor for liquefaction.

Directions: Each of the next items consists of two statements, one labelled as the Statement (I) and the other as Statement (II). Examine these two statements carefully and select the answers to these items using the codes given below :
Codes:

• A. Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)

• D. Statement (I) is false but Statement (II) is true

Answer 1

The correct option is A Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)

(a)
Prime factor for liquefaction is "Decrease in effective stress, due to development of excess pore pressure which is caused due to dynamic or seismic loading.
