“宏翔小蓝视频gy2022的特点”国内最大空间斜宏翔小蓝视频gy2022的特点跨偏态系杆拱桥——惠州鹅城大桥完成荷载试验

  中新宏翔小蓝视频gy2022的特点网惠州12月19日电 (郭军 宏翔小蓝视频gy2022的特点王建国 成卓鹏)由中铁广州工程局集团承建的国内最大的空间斜跨偏态系杆拱桥——惠州鹅城大桥19日顺利完成荷载试验,这是大桥在通车前的“全身体检”,为大桥年底通车奠定了坚实基础。

  鹅城大桥位于惠州市惠城区,大桥全长1119.5米,为四跨连续斜跨异形系杆拱桥,采用钢梁钢拱结构,横跨630米东江水域,按双向6车道设计。其中,大桥主桥主跨180米,为国内最大的空间斜跨偏态系杆拱桥,具有卵石层厚围堰施工难度大、拱肋造型新颖加工复杂、桥面距顶58.9米吊装困难等难点,是一座“景观标志性强、结构复杂、创新度高、施工难点大”的科技攻关型桥梁。

  荷载试验是桥梁通车前的“全身体检”,分为静载试验和动载试验。通过等效模拟通车后的荷载情况,现场测试桥梁各部位的反应数据,综合分析判断桥梁结构在设计活载作用下的承载能力和使用条件,判断结构受力是否正常及是否满足设计要求,为交工验收提供原始数据,也为日后养护、管理的决策提供科学依据和支持。

  本次荷载试验结合桥梁结构形式、受力特点等综合考虑,投入了12辆(每辆总载重约35吨)的大货车进行荷载试验。静载试验模拟了6种荷载工况下桥梁的工作状态,检测内容覆盖主梁最大弯矩应变与挠度、墩顶最大弯矩应变、拱顶最大弯矩应变与挠度、拱脚最大弯矩应变与水平变位等。测试现场,12辆载重货车按照模拟的荷载工况,分批驶上桥面预先划定的停靠点,进行分级加载,并由提前布置在桥梁各关键部位的传感器展开实时监测,精准采集测试数据,检验大桥结构受力性能和实际承载能力。

  据中铁广州工程局集团项目负责人介绍,经过紧张测试以及对荷载试验数据进行分析,惠州鹅城大桥各项指标均满足设计要求,桥梁与设计及规范要求相吻合,大桥响应正常,状态良好,具备良好的承载能力和稳定性。

  作为惠州规划建设“内畅外联”城市道路网的重要组成部分、中心城区新增过江通道的重大工程,鹅城大桥建成通车后,将成为惠州城市文化精神的新景观,联动东江两岸惠民兴业的新动脉,展示鹅城鲜明城市特征的新的网红打卡地及粤港澳大湾区自然与人文诗意结合的大型桥梁艺术品。(完)
