  1. List-I below gives the possible types of failure for a finite soil slope and List-II gives the reasons for these different types of failure. Match the items in List-I with the items in List-II.
    List - I
    P Base failure
    Q Face Failure
    R Toe Failure
    List - II
    1. Soils above and below the toe have same strength
    2. Soil above the toe is comparatively weaker
    3. Soil above the toe is comparatively stronger

    OP doesn’t cut Mohr’s circle tangentially
    ∴ OP is the live represented vertical stand base.

    Correct Option: A

    OP doesn’t cut Mohr’s circle tangentially
    ∴ OP is the live represented vertical stand base.


  1. There are two footings resting on the ground surface. One footing is square of dimension ‘B’. The other is strip footing of width ‘B’. Both of them are subjected to a loading intensity of q. The pressure intensity at any depth below the base of the footing along the centre line would be

    L/B of square footing = 1
    L/B strip footing = ∞
    ∴ Pressure intensity is large for square footing and small for square footing.

    Correct Option: C

    L/B of square footing = 1
    L/B strip footing = ∞
    ∴ Pressure intensity is large for square footing and small for square footing.
