Abstract
Cable-stayed
bridge
has
developed
rapidly
in
recent
decades,
its
main
force
component-based beams, the main tower and look for the external prestressing cable-stayed. Due
to
the
large
capacity
of
cable-stayed
span,
compact
structure
and
beautiful,
clear
force,
aerodynamic stability, simple structure type, etc., is becoming one of the most important bridge
bridge construction.
The
forward
direction
of
the
light
hanging
basket
of
foreign
and
domestic
aspects
of
the
design and use of hanging basket has accumulated a wealth of experience in the Cradle of the
design
forms,
the
number
using
a
lot.
Given
the
importance
of
hanging
basket
and
a
larger
amount,
it
is
now
necessary
also
entirely
possible
that
summarize
the
advantages
and
disadvantages
on
the
basis
of
existing
Cradle
be
improved
and
optimized,
but
also
to
the
high-strength,
lightweight
development.
Cantilever
construction
was
initially
parallel
truss
hanging basket, then gradually developed into a diversified, more compact structure, force more
reasonable, more convenient construction, applications are more and more widely.
