Total questions: 10
Worksheet time: 8mins
What is associated the idea Lateral Earth Pressure?
To the lateral pressure that earth causes over the airs.
To the lateral weight that acts over the instesticial spaces in the ground.
To the earth pressure that gound retain.
To the earth pressure that acts on a retaining wall.
Although much of the research upon the topic earth pressure in the ground has been performed in the last 200years, keep still existing great remarks over the fundamental approaches formulated by these two guys _______ and __________.
Coulomb 1776 and Galileo 1857
Coulomb 1776 and Rankine 1857
Marie Curie 1776 and professor Nanclares 1857
professor Nanclares 1776 and Rankine 1857
Rankine’s theory of lateral earth pressure can be applied to
Cohesion less soil
Cohesive soil
Fine grained soil
Coarse grained soil
Based on the assumptions of Rankine’s theory, the soil mass is
Stratified
Submerged
Homogeneous
All of the mentioned
If the sand filled behind the retaining wall with saturated water with water, then the possible lateral pressure is
Lateral pressure due to retaining wall
Lateral pressure due to submerged weight and Lateral pressure due to water
None of the mentioned
All of the mentioned
What will be the coefficient of earth pressure at rest for a rigid retaining wall, If the backfill consists of cohesion less soil having φ = 26°? (Hint, Ko = 1-sin φ)
0.1295
0.6552
0.5616
0.7383
When a retaining wall moves away from the back-fill, the pressure exerted on the wall is termed as
Passive earth pressure
Swelling pressure
Pore pressure
Active earth pressure
The earth pressure for the design of bridge abutments is taken as
Active thrust
Passive thrust
Thrust in rest condition
None of above
For the determination of earth pressure, Coulomb's wedge theory assumes that
the back of wall is smooth and vertical
the soil is non homogeneous and anisotropic
the slip surface is circular
the wall surface is rough
Cohesion in soil
decreases active pressure and increases passive pressure
decreases both active and passive pressure
increases the active pressure and decreases the passive resistance
increases both active and passive pressure
