摘　　要：简要介绍了软土地基桩侧负摩阻力产生的原因以及工程危害性,重点综述了近年来国内外在理论计算、数值模拟、物理模型试验和现场试验四个方面的研究成果,并总结和分析了几种常用理论计算方法及其优缺点;对目前常用的减少桩侧负摩阻力的工程优化措施进行了概述和分析,并探讨了桩侧负摩阻力在建筑物纠倾工程中的应用,指出通过调整桩侧负摩阻力进行纠倾可为负摩阻力的应用提供了一个良好的开端;针对当前桩侧负摩阻力领域的研究现状,对今后的研究发展方向进行了展望。该研究可为今后的相似研究提供参考。This paper briefly introduces the cause of the negative skin friction of pile in soft soil foundation and its harmfulness to the construction project, reviews the research situation of theoretical calculation, numerical simula tion, physical model test and field test in recent years, sums up and analyzes several common methods for theoretical calculation and their merits and demerits, and generally describes and analyzes the optimization measures of the con- struction project currently used for decreasing negative skin friction. Then, the paper discusses the application of negative skin friction of pile to correcting the building inclination by adjusting the negative skin friction, which sup- plies an excellent beginning for the application of negative skin friction. Finally, the paper prospects the trend and direction of the future research on negative skin friction of pile in combination with the current research status, which can provide useful references for similar researches in future.
