The stress of soil (kN/m3) is influence by the _______and __________.
force and depth
density and area
unit weight and area
unit weight and depth
The capillary action takes place above ground water table up to 1.3 m height. Assume the unit weight of water is 10 kPa. Calculate the pore water pressure at the surface of ground water table.
-13 kPa
-10 kPa
0 kPa
13 kPa
The followings statement is associated to the possible increase in effective stress at certain depth except
ground water table decrease
ground water table increase
the existence of capillary action
the changes from loose to a dense state of soil
1. The soil with a unit weight of 19 kN/m3 with a thickness of 3m is carried a load from an embankment of 75 kN/m2. Determine the total stress at the ground surface.
132 kN/m3
132 kN/m2
75 kN/m2
57 kN/m2
1. The soil with a saturated unit weight of 19 kN/m3 with a thickness of 3m is carried a load from an embankment of 75 kN/m2. If the ground water table is at the ground surface, determine the effective stress at the bottom layer of soil. Assume unit weight of water is 10 kN/m3
102 kN/m3
132 kN/2
75 kN/m2
102 kN/m2
Rate of water flow in soil is indicate by
Cohesion
Permeability
Moisture content
Conductivity
In which state of energy will water move?
high energy to low energy
low energy to high energy
high energy to high energy
low energy to low energy
Soil that is saturated is said to have a water potential(pore water pressure) of...
Zero
Negative
Positive
Sinkholes is happen due to
natural causes
human interaction in underground
pipe leaking
all
Permeability is address as follows ACCEPT
a coefficient to rate the accelaration of water flowing
in clay, the k value is very small
can be address as k
increases k value for lower porosity, n
Water in soil related to
study of ground water table (GWT) in swamps only
97 %fresh frozen water in underground
study to avoid landslide, sink holes and many more
Capillary water is
water that can seep into vadoze zone
pemeability of water into ground
ground surface water table (GWT)
Your lecturer name is
(a)
Coefficient of permeability is benefit to
assess drainage characteristics of soil
assess rate of consolidation
to predict rate of settlement of soil bed
all of them
Select the CORRECT soil layer for this statement;
A 4 m clay layer underlaid by the 2 m sand layer. The groundwater table is at the surface of the clay layer.
