Construction—APAC—India—Slope Stabilizations
The Chenab Bridge: DYWIDAG Systems stabilize impressive Slopes
for the World’s highest Railway Bridge
Traveling around the mountainous region of Jammu and Kashmir in northern India has always been
difficult. In order to considerably shorten travel times, the Indian Government decided to build a new,
345km long railway route from Jammu to Baramulla.

This project also includes a new, 1,315m
long railway bridge across the Chenab River
near the town of Katra. Once completed, the
bridge, the 469m long main span of which
reaches a height of 359m above the River
Chenab, will be the world’s highest railway
bridge.
As the bridge has a design life of 120 years,
the General Contractor needed a proven,
reliable system for stabilizing the Chenab
Valley’s massive slopes that have angles
between 43° and 77°.

Furthermore, the system was also required
to be earthquake-resistant. DSI proposed
its double corrosion protected (DCP)
DYWIDAG Bar Anchor System consisting of
WR DYWIDAG Bars, which is known around
the world for its quality and reliability.
Due to the fact that the construction site
is located in one of the most remote and
difficult to reach parts of India, DSI together
with its partners decided to produce the
DYWIDAG Anchors in a field factory directly
on site using high-quality materials in order to
ensure the highest possible quality. This way,
the permanent corrosion protection can be
applied in the close vicinity of the site, and the
corrosion protection applied on the DYWIDAG
Systems is not exposed to damage during the
long road transport to the site.
In addition to the supply of the DYWIDAG Rock
Anchors including accessories, the scope
of DSI and its Indian partner company also
included the supervision of on-site production,
the installation and the stressing of the bar
anchors as well as the supply of the necessary
equipment.
