| 中文摘要:首先对河北廊坊天堂河穿越工程的概况和施工难点进行了介绍；然后针对工程需要提出了注水平衡法，并对其进行了理论分析；最后对施工过程和结果进行了分析介绍。施工实践证明了理论分析的正确性，且表明：非开挖施工时，在管道中注入适量水能平衡管道所受浮力，减小管道所受摩擦力，能达到减小管道回拖力的目的。 |

| Abstract:In this paper, the general situation and difficulties of the Tiantang River crossing project are introduced firstly; then Watering Balance Method WBM is put forward with theoretical analysis on it; finally, the construction process and results of the whole project are introduced and analyzed. The construction practice proves the theoretical analysis is correct and reveals that during the construction process, buoyancy force can be balanced by injecting water into the pipeline to decrease its friction and pulling force. |
