基于上限塑性公式，提出了一种估算负压沉箱锚杆水平承载能力的简化分析方法。这种简化将分析局限于均匀和线性变化的不排水强度剖面中的沉箱；然而，其计算效率允许快速评估影响承载能力的一些参数。通过与更严格的有限元解的比较，证明了简化公式的有效性和局限性。一系列敏感性研究证实了不同土壤条件和荷载参数的影响。版权所有©2003 John Wiley&Sons，Ltd.
A simplified method of analysis for estimating lateral load capacity of suction caisson anchors based on an upper bound plasticity formulation is presented. The simplification restricts the analysis to caissons in uniform and linearly varying undrained strength profiles; nevertheless, its computational efficiency permits quick evaluation of a number of parameters affecting load capacity. The validity and limitations of the simplified formulation are demonstrated through comparisons to more rigorous finite element solutions. A series of sensitivity studies demonstrate the effects of various soil conditions and loading parameters. Copyright © 2003 John Wiley & Sons, Ltd.
