Which of the following statement is wrong?

(ക) 117 cantilever retaining walls, the stem acts as a vertical cantilever; whereas in
counterfort retaining walls it act as a continuous slab

(0) Weep holes are provided in thé retaining walls to reduce the development of
excessive lateral pressure on the walls

(C) Fine graded soils are usually recommended as a backfill material as it reduces the
earth pressure against retaining walls

(D) The basic difference between counterfort and cantilever retaining walls is in the
calculation of bending moment and shear force

Which of the following statements is TRUE?

(ಗಿ) The depth of exploration required at a particular site is mainly governed by the
depth of the influencing zone

(18) Auger bring is recommended where depth of sampling is high
(C) Wash boring is suitable for obtaining undisturbed samples above water table level

(D) Undisturbed soil samples are used to determine the index properties of soil like
grain size, plasticity characteristics ete

‘The maximum rate at which a soil in any given condition is capable of absorbing water’ is
termed as :

(4) Infiltration rate (B) Infiltration capacity
(C) Absorption capacity (D) Sorption rate

‘Capillary fringe’ refers ‏٠ہ‎
‎(ಸಿ) Zone just above the water table where moisture content is maintained by
capillarity
(3) Zone just below the water table where moisture content is maintained by
percolation
(C) Zone below the soil moisture zone

(D) Zone just below the sub-surface where moisture content is maintained by
infiltration

The plotting of linear form of standard infiltration capacity curve represents a straight line
with a slope equal to :
