摘　　要：流砂层封水一般采用注浆、冻结等单一施工技术。对扬州市城市南部快速通道荷花池隧道泵房北侧的灌注桩和隧道结构、灌注桩和三轴搅拌桩之间严重扰动的流砂层,采用先注浆、后冻结联合技术治理,竖井和泵房封水取得良好效果,对类似工程项目有借鉴意义。Water sealing of a quick sand bed generally would be conducted with a grouting,ground freezing and other single construction technology.A first grouting and then ground freezing combined technology was applied to control the serious disturbance quick sand bed between the cast in place piles and tunnel structure,the cast in place piles and three axes mixed piles at the north side of the pumping chamber in the Hehuachi Tunnel of the south fast channel in Yangzhou City.Good results were came from the water sealing of the tunnel shaft and pumping chamber and could be the reference significances to the similar engineering projects.
