摘　　要：通过计算，从附加荷载、桩的负摩擦力、设计三个方面分析了长东黄河铁路一桥东引桥1号～3号墩沉降原因，并详细介绍了较为复杂的桩负摩擦力的计算过程；计算结果证明，淤灌防洪大堤产生的附加荷载和由此产生的桩负摩擦力是产生沉降的主要原因。Passes the calculation, from the additional load, pile negative friction, designing third aspects analyzes Changdong the Yellow River No. 1 Bridge east leading bridge No. 1 --No. 3 frusta settlement reason, detailed introduces complicated pile friction calculate process, compute result proof that the additional load of flood control of big dike and negative friction that produce is a main reason of settlement.

关 键 词：桩 沉降 附加荷载 负摩擦力
