Introduction
PANTEX Lattice Girders have been
developed for special demands in the
field of Tunneling. The PANTEX system
has been extensively tested and used
successfully for numerous tunnel projects
throughout the world.
PANTEX Lattice Girders ensure an
immediate support in the open span area.
Contrary to standard solid-web girders,
PANTEX Lattice Girders are entirely
integrated in the shotcrete lining; porous
zones and shotcrete spray shadows are
avoided.
The load-bearing capacity of PANTEX
Lattice Girders has been investigated with
various loading tests and by numerical
analysis. Flexibility regarding geometry
and bearing capacity characterizes this
passive support system for underground
applications.
