摘　　要：西江航运干线南宁(牛湾)至贵港3000吨级航道工程及平陆运河均按内河Ⅰ级航道标准建设,黎钦铁路飞龙郁江特大桥位于西江航运干线平塘江口至六景航道之间,现状铁路桥梁仅满足Ⅱ级航道通航要求,将直接影响开通后效益的发挥,故需要对该桥梁进行改建,进而引起两端铁路连接线进行改建。本文结合桥梁选型,从线路规模、通航条件、社稳影响因素、工程投资等方面考虑,对该段线路改建方案进行综合比选,提出了推荐方案,为类似工程项目提供参考和借鉴。Both the 3000-ton-class waterway project from Nanning(Niujuanwan)to Guigang on the main line of the Xijiang River shipping route and the Pinglu Canal are constructed in accordance with the Class I inland waterway standard.The Feilong Yujiang River Grand Bridge on the Liqin Railway is located between the waterway from Pingtang River Estuary to Liujing on the main line of the Xijiang River shipping route.The current railway bridge only meets the navigation requirements of the Class II waterway,which will directly affect the realization of the benefits after its opening.Therefore,it is necessary to reconstruct this bridge,and consequently,the railway connecting lines at both ends also need to be reconstructed.In combination with the selection of bridge types and considering aspects such as the scale of the line,navigation conditions,social stability influencing factors,and project investment,this paper comprehensively compares and selects the reconstruction schemes for this section of the line,puts forward the recommended scheme,and provides references for similar engineering projects.
