Abstract：Research purposes：Qingyang port is the channel four．The Qingyang port bridge is a basket handle arch bridge of Nielson system with a single span of 96m．In order to meet the requirements of navigation，the arch first and beam late construction method is used．This article introduces the design of 96m basket handle arch bridge of Nielson system．The stress of the main structure of the bridge is calculated according to the established finite element model of bridge actual construction phase．It explains arch first and beam late construction method．
Research conclusions：Calculation results show that each cross section stress of the main bridge structure is in the corresponding material allowable stress range and meets the requirements of the code．Adjusting the stiffness of foundation，can change the displacement of arch rib span，arch rib steel pipe stress，concrete stress and rod stress．It needs sufficient strength and rigidity because of the first stress of steel tube arch rib by method of arch first and beam late．This method without support construction meets the navigation requirements and has great social benefits and has great social benefits．The conclusion can be applied to similar projects．
