| 摘 要： | 鉴于现有承载力确定方法存在的不足之处，通过对大直径扩底桩承载力确定原则的探讨，给出了按沉降变形控制确定承载力的方法，并推导出了确定无静载试验桩承载力的计算公式，工程实例验证表明，按作者提出方法得到的结果与工程实测值符号较好，能充分发挥大直径扩底桩的潜力，可以供工程设计时参考使用。

| Abstract: | To overcome the defects of the present method, a new method to determine the bearing capacity of pile according to settlement is presented by discussing the criterion of bearing capacity, and the formulae for calculating the bearing capacity of pile without dead load experiment is derived too. The results obtained by this method fit well with the field test results, and the potential bearing capacity of large diameter belled pile can be utilized fully, so it can be used as a reference in engineering design. |
