摘　　要：北京某地下工程与地铁连接通道施工中,针对富水砂层复杂地质条件下浅埋暗挖隧道下穿河道危险性大、安全风险高等问题,采用围堰导流、超前深孔注浆、水平旋喷注浆及信息化设计施工等关键技术,创造了稳定可靠的干地施工条件,保证了河道安全和施工质量。During construction of a passageway of a basement project connecting to a subway station,there were high danger and safety risk in the shallow-buried excavation tunnel undercrossing a river course with complex geological conditions where the stratum was rich of water and sand.Some key techniques,such as cofferdam diversion,deep hole grouting,horizontal rotary grouting and information-based design and construction,etc.,were adopted to create a stable and reliable dry land construction conditions.River course safety and construction quality were guaranteed.
