桩侧负摩阻力对桩基产生下拽力，对桩基的承载力和沉降均不利，对受负摩阻力桩基进行设计时，需要正确估计桩基负摩阻力的大小及中性点的位置。开发颗粒流程序来模拟单桩负摩阻力的工作性状，验证中性点的位置并对桩侧土体细观特性进行分析。

Negative frictional resistance on pile side produces downdrage to pile foundation, detrimental to both bearing capacity and settlement of pile foundation, so the magnitude of negative frictional resistance of pile foundation of the position of neutral point should be estimated correctly when designing pile foundation under negative frictional resistance. This paper develops the particle flow code to simulate working properties of single-pile negative frictional resistance, verifies the position of neutral and analyzes microscopic characteristics of soil mass on pile sides.
