摘要
相比于传统基础,桶形基础作为一种新型的浅海基础形式具有诸多明显的优点,但其使用历史相对较短,设计理论也还不够完善。基于此,利用三维有限元方法和极限平衡方法对单桶形基础的水平承载力进行了数值计算和理论推导,并基于分析结果,给出了适用于估算饱和软黏土地基中单桶形基础水平承载力的简便公式,为指导工程设计提供一定的参考意见。
Though bucket foundation used as a new type of foundation in shallow water can have significant advantages over conventional ones, the history of its development is relatively short and the method of design is still not mature. In this situation, the authors obtain the horizontal bearing capacity of bucket ~foundation based on three-dimensional finite element method and limit equilibrium method. According to the result, a simple formula for evaluating the horizontal bearing capacity of bucket foundation on saturated soft clay ground is given for engineering practice.
