“1819岁macbookpro高清”广东阳江最1819岁macbookpro高清长跨海大桥通车

  中新1819岁macbookpro高清网广州12月26日电 (1819岁macbookpro高清蔡敏婕 葛世超)广东阳江海陵大堤至溪头段(含阳江港大桥)公路工程26日正式通车,为阳江经济社会发展注入动力。

  阳江海陵大堤至溪头段(含阳江港大桥)公路工程起点位于阳江高新区进港大道,终点至阳西县溪头镇省道S278,全长24公里。

  其中,控制性工程阳江港大桥全长约4.8公里,主塔高158.7米,全线采用双向六车道标准设计,设计时速为60公里至80公里,是阳江市境内最长、最大的跨海大桥。

  阳江港大桥建成通车后,将结束阳江市区至阳西溪头、上洋等镇绕行80公里的历史,出行时间也将从原来的一个半小时缩短到半个小时。

  作为广东滨海旅游公路阳江先行段重要工程,该项目也是阳江交通和经济社会高质量发展的“关键一纵”。它将阳江港经济区和阳西丰头港经济区连为一体,形成贯通沿海地区的便捷通道,对助力阳江市旅游业及沿海经济发展、构建大交通格局、主动融入大湾区具有重要意义。

  阳江港大桥初步设计四跨连续刚构桥,基于港区建设和城市交通长远发展的需要,大桥实行远期预留航道升级,桥梁结构设计优化为独塔双跨斜拉桥,大幅调整其预留通航尺寸。

  “设计变更后的主航道海轮通航能力将由原先设计的1000吨提升到5000吨,通航净空由29米提高至37米,通航净宽由148米提升至183米。”保利长大阳江海溪项目部总工程师刘正祥介绍。

  阳江港海域地质条件复杂,海床底软基层深厚,为保质保量地赶进度,项目团队采取了一系列的技术手段,攻克了深水桩基和承台施工、墩柱高空作业、主塔钢节段及钢箱梁高空吊装等施工困难,刷新了多项“纪录”。(完)
