摘要

港珠澳大桥岛隧工程的沉管隧道有219个节段接头,其中60%水深超过40 m。每个节段接头的环向长度90 m。为了保证可注浆止水带的止水效果,对止水带的使用进行了系统的改良。2013年5月至2017年3月,33个管节已在水下安装,节段接头部位均未发现漏水。文章讨论可注浆止水带的使用改良的方法与原因。
        The immersed tunnel in Hong Kong-Zhuhai-Macao( HZMB) island and tunnel project has 219 segment joints,of which 60% is 40 m below water. Each joint has a circumferential length of 90 m. To ensure the effectiveness of injectable waterstop,a systematic improvements were made to the use of the waterstop. From May 2013 to March 2017,all tunnel elements were installed below the water,no leakage is found at the segment joints up to now. This paper discussed the improvements of the way of using injectable waterstop and the reason.
