Deng marine environment challenge, island bridge engaging portion and other lower positions of bridge floor design altitude to bridge engineering for sea-crossing, bridge
There are hidden danger unrestrained on wave in face, constitute a threat to bridge floor traffic safety.
Occur to reduce wave on bridge floor, can raise bridge floor design altitude, or by building breakwater in bridge location side of heading sea
Etc. forms abatement reach the wave of bridge location, but often these counter-measures are difficult to carry out since cost is high, it is big to influence.
Traditional bridge floor guardrail primary protection object is the vehicle and pedestrian on bridge, is armored concrete or steel construction mostly,
Typically hollow structure.In recent years, to improve bridge floor driving wind environment, bridge air partition and Bridge guardrail is combined, will be protected
Column column increases reinforcement, installs multiple tracks air partition item in the upper end of the column, has certain air permeability rate between air partition item.As it can be seen that traditional
Bridge floor guardrail and its air partition structure do not have wave resistance effect.
Bridge floor guardrail is located at the bridge edge of a wing, has natural advantage as the main structure of bridge floor wave resistance, compared to lift
The modes such as high bridge floor design altitude, setting breakwater have many advantages, such as low cost, easily implement, but how traditional guardrail to be transformed
At can stop wave panting action repeatedly, and have it is antifatigue, can the good structure of durable, easy-maintaining and landscape effect, need
Carry out innovative design.
