摘　　要：以广州地铁工程大坦沙站～如意坊站盾构区间穿越珠江为例,结合工程地质条件,介绍了盾构隧道下穿珠江的施工技术,并对盾构穿越珠江施工风险进行了详细分析,并针对性地提出了风险应对措施,施工风险控制实践表明,盾构穿越珠江的风险得到了有效的控制,可为今后类似盾构隧道穿越江河工程的安全风险控制与施工提供指导。Taking as an example the project in Guangzhou metro interval shielded engineering from Datansha Station to Ruyifang crossing the Zhujiang River,the shield tunnelling construction technique was introduced combined with the engineering geological conditions.And analysis on the interval construction risks was carried out in detail and the risk countermeasures were put forward.It was provided that the risk of shield crossing Zhujiang River construction was controlled effectively.These experiences could be referenced for future similar shield tunnel project.
