The Sixth Jianghan Bridge in Wuhan province are bridge-tower self-anchored suspension bridge of which the de-sign of the main girder adopted steel-concrete composite str-uctures and the instal ation of steel girders applied the push te-chnology. Under the influence of river navigation, the largest span of thrusting reached 90 m, so the construction was dif-ficult. Based on the design profile and launching technology, this paper analyzed the difficulties and key controlling points of the technology and put forward specific control measures.
