THE HOISTING CONSTRUCTION TECHNIQUE OF WUHAN SHAHU LAKE BRIDGE

Youyi avenue overpass of Wuhan Shahu Lake Bridge,which spans over the first tunnel of the Yangtze River,faces great challenges in construction due to its large traffic volume and weak ground base.The construction scheme is optimized by installing large segmental steel box girders according to terrian condition and other related requirements so that the impact on the road traffic will be reduced,construction period shortened,the quality of construction ensured and meanwhile the safety of the tunnel well guaranteed.The design is testified and proves to be effective by re-examine the linearity of the bridge and the fastness of the ground base after the installation of the steel box girders.
