【摘要】 桶形基础的承载特性,由于埋深范围和筒内包裹大块土体,而显著区别于桩基和普通浅基础。水平承载力计算与桩基存在显著的差别。本文结合了API规范中有关桩基和浅基础承载力的有关规定,结合桶形基础的特点,基于刚体极限平衡理论,提出了桶形基础承载力计算的一种方法,并用于分析垂直荷载与泥面弯矩的对水平承载能力的影响。更多还原

【Abstract】 The mechanism of the bucket foundation is quite different from the pile foundation or general shallowfoundation, for there is a large sums of soil inside the bucket. The method of horizontal capacity calculationof the foundation is different to the pile foundation. Based on the limit equilibrium theory, a method toapproximately estimate the capacity of the foundation has proposed here and has applied to analysis theaffection to the horizontal capacity from the vertical load and the bending moment which is imposed on thefoundation.更多还原
