| 總結: | Knowledge
of
retaining
wall
design,
in
this
case
specifically
cantilever
wall
is
essential
for
the
construction
in
areas
where
ground
retention
is
needed.
Construction
of
retaining
wall
is
often
backfilled
with
sand
due
to
the
high
friction
angle
and
strength
of
the
soil.
However,
backfilling
can
induce
lateral
pressures
on
the
wall,
which
will
affect
the
stability
of
the
wall.
In
Eurocode
7,
there
is
an
introduction
of
partial
factors
for
various
actions
and
resistance
acting
on
the
cantilever
wall.
These
forces
will
produce
stabilizing
effects
as
well.
The
project
was
carried
out
in
a
basis
of
identifying
the
mechanism
that
governs
the
failure
of
the
wall.
The
mechanisms
are
namely,
Base
Sliding,
Overturning
about
the
toe
of
the
wall
and
Bearing
Capacity.
The
analysis
also
utilizes
Microsoft
Excel
spreadsheet
to
identify
the
failure
mechanism
of
the
retaining
structures
design
for
a
given
wall
base
width.
Satisfaction
for
all
three
mechanisms
will
also
be
achieved.
A
comparison
of
the
retaining
wall
design
between
the
newly
introduced
Eurocode
7
and
British
Standards
will
be
carried
out.
Given
the
example
in
Eurocode
7,
Chapter
9,
there
are
limitations
on
the
analysis
method
as
the
Overturning
about
the
toe
will
never
be
the
governing
failure
mechanism.
This
paper
will
present
a
detailed
study
of
the
above
and
provide
a
spreadsheet
that
can
correctly
and
accurately
gives
solutions
to
retaining
wall
design.
The
limitations
of
the
retaining
wall
study
will
also
be
discussed. |
