摘　　要：分析了影响单桩水平承载力以及位移的主要因素—桩长、桩径、竖向荷载、桩身抗弯刚度、桩身截面积、桩顶形式等。在影响单桩承受水平荷载作用性状的诸多因素中,桩长的影响相对较大。在单桩的桩长范围内,桩长越长其水平承载能力越高。通过分析比较,为改进和提高桩基础结构设计的安全性和经济性提供了依据,可供工程应用参考。is analyzed the factors influencing the horizontal bearing capacity of a single pile,such as pile length,pile diameter,vertical load,bending stiffness of pile,cross-section area of pile,pile top design,etc.Pile length has a greater influence on lateral load-bearing capacity of ram-compaction pile as compared to other factors.Lateral load-bearing capacity of pile is increased by lengthening of pile length.Whose analysis provides a basis for security and economy of designing pile foundation structure.So the result may be useful in practical design.
