2.6 Splay Saddles
The splay saddles are designed to steer the spatial
main cable into a simpler 2-dimensional layout at the
anchorage chambers. This is done to simplify the
anchorage chamber layout by avoiding “rotated”
strand shoe geometry. The strands are divided in the
saddle by a tailor made fill block which deviates the
strands to their respective cable anchorage points.
2.7 Anchorage
The cable anchorage consists of splay chamber and
anchorage hall which is a mountain hall 40m long and
15m high. It is the same for both splay chambers. The
main cables pass over a splay saddle and are attached
to an anchor block which in turn is attached to a
tension cable.
There are 20 tension cables grouted to a casing which
is bored 30m through rock to the anchorage hall. In
the anchorage hall, there is a concrete slab that is
2.5m thick, 37m long, and 13m tall, where the tension
cables for the two main cables are anchored;
altogether 42 at Karistranda and 44 at Øyjord.
