中新网荆州7月29日电 (卢家国 乔朝辉 王梦媛)长江荆州段,两座世界级大桥在一西一东,正加速“生长”。7月28日,李埠长江公铁大桥与观音寺长江大桥施工现场,主塔高耸、吊机凌空,与既有荆州长江大桥形成“三桥并立”的过江新格局,彰显中国桥梁“智造”实力。
李埠长江公铁大桥地处荆州中心城区上游西侧,观音寺长江大桥则位于城区下游东侧。两座在建大桥将现有的荆州长江大桥夹于中间,共同构成荆州过江新通道。

走进李埠长江公铁大桥建设现场,用于梁段悬拼架设的蓝红配色大型桥面吊机整装待命,项目持续稳步推进。该桥全长7.91公里,主跨1120米,是世界最大跨度公铁双层斜拉—悬索协作体系桥梁,计划2027年建成通车。
项目创新实现“上层高速、下层高铁+一级公路”一桥三用,破解大跨度、高通航、多交通制式协同的世界级难题。作为荆州首座双层公铁合建长江大桥,李埠大桥承载着补齐西部过江通道短板、畅通江南江北联动、完善公铁联运格局的重要使命。
该桥采用斜拉—悬索协作体系,兼具斜拉桥刚度大、悬索桥跨越能力强的双重优势。中建三局项目技术总监刘峻珲表示,悬索体系确保主跨一跨过江,满足大跨度需求并保障航道畅通;斜拉体系则着力提升桥梁承载能力与结构稳定性,两项体系协同配合,共同确保桥梁安全运行。
与此同时,项目在桥塔施工中率先引入5G塔吊装备,属国内同行业首次应用。据湖北交投荆楚建设公司总经理雷宗建介绍,项目团队自主研发轻型智能造塔机与5G远程塔吊集控系统,可实现减员40%、综合效率提升30%的显著成效。
位于李埠大桥下游的观音寺长江大桥施工现场同样一派繁忙。宽阔桥面凌空悬于江面之上,梁体逐节向江心延伸,施工团队持续推动这座世界最大跨径公路斜拉桥朝着今年年底合龙的目标稳步迈进。

观音寺长江大桥全长1860米,为双塔11跨混合式组合梁斜拉桥。作为“一跨过江”的南北交通枢纽和湖北省“一芯两带三区”区域发展战略的重要支点,大桥建成后将大幅缩短武汉都市圈与宜荆荆都市圈之间的通行时间,促进“宜荆荆恩”城市群互联互通。
桥面混凝土梁宽达41米、高4米,最重的一块梁段达到605吨。为将其从工厂运至江面,并精准安装,项目团队采用超高性能混凝土组合梁预制拼装技术。此外,项目团队还在国内首次应用自主研发的轻型钢-UHPC组合桥面板,比传统混凝土桥面板减重近两成,大幅降低斜拉索负担。斜拉索采用2100兆帕的平行钢丝,单根索能承受的拉力更大。“一头减轻重量、一头增加拉索拉力,桥面会更稳。”湖南路桥观音寺长江大桥项目总工杨新湘称。

两座世界级桥梁——李埠长江公铁大桥与观音寺长江大桥在荆州城区一西一东巍然对峙。两座大桥建成后,荆州“三桥并立”的过江新格局将从蓝图化作通途,赋能长江经济带发展。(完)
