摘要
阐述了桩基负摩阻力的概念,指出了负摩阻力对桩基受力的不利影响。从土力学桩土关系、有效应力原理、土体固结等基本原理的角度,分析了负摩阻力的形成机理,并提出了相应的防治对策。
This paper discusses the concept of negative skin friction of pile foundation and points out its negative impact to the force on pile foundation. From the perspectives of relationship between piles and soil,effective stress principle,soil consolidation etc.,it analyzes its formation mechanism and control measures.
