摘　　要：浅述了桥梁桩基设计中桩侧土负摩阻力的产生机理、产生原因及影响负摩阻力的因素,介绍了桩基中性点位置的确定、负摩阻力计算等问题,并综述了有效消减负摩阻力的措施。The paper superficially discusses the mechanism of negative friction of pile lateral soil in design of bridge pile foundaton,the reasons for its occurrence and the factors causing it. It introduces yet determination of neutral point of pile foundation and calculation of negative friction. In addition it aslo summarizes measures for effectively eliminating and readucing the negative friction.

关 键 词：桩基设计 负摩阻力 中性点
