摘　　要：天津某排水管道深基坑采用整体钢板桩支护的方案施工,根据土质条件进行了土压力计算。经计算确定钢板桩埋深和支撑反力,验算坑底隆起满足要求,坑底管涌不会发生。对围檩受力、支撑杆受力计算,也均能满足要求。经工程实践验证,该设计方案科学合理,安全可靠。The integral steel sheet piles is carried out in the construction of a deep foundation pit of a drainage pipeline project in Tianjin. Theearth pressure is calculated according to the soil conditions. After calculating, the depth and supporting force of steel sheet pile is defined. Bychecking, the bottom of the pit uplift, bottom tube puddles will not happen. Force on the Wai, and support force, but also can meet the requirements.The engineering practice verify that the design is scientific and reasonable, safe and reliable.
