斜拉桥索导管的施工监控

Construction Control of Cable Anchor Tube in Cable-stayed Bridges

斜拉索是斜拉桥的重要组成部分 ,是弹性连续主梁的弹性支座 .其到位精度直接影响主梁的受力 ,所以它的施工监控就十分重要 .结合仙桃汉江公路大桥索导管的施工监控过程 ,对索导管的场内加工、安装就位、成品验收等一系列监控流程作了详细介绍 ,并提出一些积极建议 。

Cable is one of the importantpartsin the cable-stayed bridges. It' s the spring-bearing of the continuous girder,the place of which strongly influences the state of the girder,therefore,its construction control of the cable anchortube(CAT) isvery important.Forthe construction control of CAT of Xiantao Hanjiang River Highway Bridge,its technological process—— the making,the setting,the checking of CAT is introduced and positive suggestions are made,which can push the construction of the cable-stayed bridge forward.
