Hi
dawit
sure
I
can
share
you
the
goggles
sheet
for
that
project
so
you
can
see
how
the
formula
work
to
get
the
number,
and
the
Google
doc
for
part
1
and
2
so
you
know
where
is
the
number
come
from,
but
I
think
each
group
have
different
number(
like
decimal,
pressure
factor,
bulb
or
get
old
data
from
part
1
and
2
from
different
numbers
)
so
it
will
lead
part
3
will
have
different
number.
There
fore
,
since
the
formula
in
the
sheet
already,
just
change
the
number
from
group
to
get
your
own
number.
Just
share
invitation
to
your
email
for
goggles
drive
doc
for
part
1
and
2
also
the
Google
drive
sheet
for
part
3.
Not
different
from
each
groups
but
because
when
we
did
the
calculation
base
in
Z/B
in
part
1
and
2,
everyone
has
different
choice
of
pressure
facture
bulb,
as
you
see
in
our
part
one,
2
members
did
the
same
case
still
have
different
number
at
the
end.
That
make
each
work
unique.
In
our
part
3,
we
supposed
to
use
our
own
number
in
part
1
and
2
but
we
decided
to
use
all
numbers
from
1
of
our
member
and
my
self
to
calculate
for
part
3
to
easy
to
keep
track
so
if
you
use
your
own
number
then
just
input
to
the
Google
sheet,
the
result
will
different
since
the
formulas
are
in
the
sheet,
already,
so
you
need
to
input
your
own
number.
Everyone
has
own
number
yes,
since
base
base
on
Z/B
value,
then
look
at
bulb
factor
diagram
here
like
this
Z/B=1.3
everyone
must
have
same
this
value
but
when
look
at
bulb
factor
I
decided
the
pressure
bulb
factor
is
0.23.
But
other
member
maybe
think
it
is
0.24
or
0.22.
the
project
like
he
will
check
where
the
number
come
from
or
not
(like
from
group
work
for
part
1
and
part
2)
so
the
only
way
to
make
part
3
make
sense
is
match
the
number
from
part
1
and
part
2
so
try
to
get
number
from
part
1
and
part
2
in
your
group
work..
I
sent
you
googols
drive
documents
part
1
and
part
2
,
also
Google
drive
sheet
part
3
my
work
in
there
too!
If
you
look
at
part
3,
we
all
used
number
from
part
1
&
2
and
for
number
in
part
1
and
2
each
of
us
have
different
numbers
because
of
the
different
pressure
factors
bulb
that
we
decided,
so
if
did
part
1
and
2
you
should
have
your
own
number
too!
And
then
just
put
in
the
number
in
the
sheet,
you
will
get
different
too
because
I
formatted
the
formula
in
there
to
get
delta
sigma
as
long
as
understanding
it
it
is
very
easy,
just
your
own
number,
because
the
steps
were
very
detail
in
doc
and
sheet.
Assume that you put 40 feet of surcharge fill at the site for 25 years. You then remove the material. The unit weight of the material is
100 pounds per cubic foot. Repeat the settlement calculations and come up with a new foundation design. Fill in the table for the new
situation. Hint: this only changes your pre-consolidation pressure. To get the new preconsolidation pressure, simply add
40(100)=4000psf to Sigma’-i.
