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。 The main factors that affect the horizontal bearing capacity and displacement of pile are analyzed, such as pile length, pile diameter, vertical load, bending stiffness of pile body, cross-sectional area of ​​pile body and pile top form. Among the many factors that affect the horizontal load behavior of single pile, the influence of pile length is relatively large. Within the pile length of a single pile, the longer the pile length, the higher the horizontal bearing capacity. Through the analysis and comparison, it provides a basis for improving and improving the safety and economy of the pile foundation structure design, which can be used for engineering application.
