摘　　要：随着我国大跨桥梁建设的发展,桥梁锚碇基础的地下连续墙施工技术要求日益突出。结合广州珠江黄埔大桥南、北锚碇的嵌岩地下连续墙施工,针对不同的工程地质条件,着重介绍了槽段划分、导墙和施工平台、泥浆系统、成槽工艺等关键施工工艺。经实践证明,采用这些施工工艺,取得了很好的经济效益和社会效益。With the development of the large-span bridges in China,more technologies for the diaphragm walls of the bridge anchorages have been demanded.According to different geological conditions,the construction technologies of south and north anchorages of Huangpu Bridge over Zhujiang River in Guangzhou were given,including the trough-dividing,guide walls, construction platforms,mud system and trenching technology.The construction technology led to satisfactory economic and of the social benefits.
