摘要

采用数值分析方法探讨不同深径比筒型基础在竖向、滑动和倾覆荷载作用下的承载特性

对比分析汉森公式、墩式深基础公式、基于土压力理论的抗滑承载力计算方法和数值计算结果之间的差异

从而明确3种计算方法的适用范围。结果表明：汉森公式法计算的竖向承载力与数值计算结果具有良好的一致性

且优于墩式深基础公式法;基于土压力理论的抗滑承载力算法与基于墩式深基础公式的抗倾承载力算法仅对深径比为0.25~1.00的筒型基础具有较好适用性。

Abstract

Numerical analysis has been conducted to examine the bearing characteristics of bucket foundations with various embedment ratios under vertical

sliding

and overturning loads. Comparative analyses between the results obtained from the Hansen formula

the caisson deep foundation formula

earth pressure-based calculation methods

and numerical simulations have elucidated the applicability ranges of these methodologies. The findings demonstrate that the vertical bearing capacity calculations using the Hansen formula align closely with the numerical analysis results

surpassing those obtained through the caisson deep foundation formula. Additionally

it was determined that the anti-slide and anti-overturning bearing capacity calculations based on earth pressure theory and the caisson deep foundation formula respectively are appropriate only for bucket foundations with embedment ratios ranging from 0.25 to 1.
