摘　　要：广州珠江黄埔大桥悬索桥北锚碇位于珠江大壕沙岛上,地下水位受潮汐影响严重,深基坑开挖风险较高,主要介绍该悬索桥北锚碇基坑开挖及内衬施工技术。The north anchorage of the suspension bridge of Huangpu Bridge over Zhujiang River in Guangzhou is located at the Big Haosha Island in the Zhujiang River, where the underground water level is severely influenced by the tide and the excavation of the deep foundation pit for the anchorage is fairly risky. In this paper, the construction techniques for the excavation and lining of the foundation pit are mainly presented.
