摘要
基于对厚承台的非线性有限元分析结果,研究了厚承台的传力机理。研究发现厚承台的传力机理符合空间桁架模型理论。在分析了厚承台承载力的主要影响因素后提出斜压杆承载力和拉杆承载力的计算公式,采用拉压杆模型计算了厚承台的极限承载力,算得承台的承载力与试验结果吻合较好。
On the analysis of thick pile caps by nonlinear finite element method, the transfer mechanism of thick pile caps is studied in this paper. The study shows that transfer mechanism conforms to the space truss model. The main factors which influence the ultimate bearing capacity of pile caps are also studied in this paper, and the formula to calculate the bearing capacities of struts and ties is put forward, the ultimate bearing capacity of thick pile caps is calculated using the struct-and-tie model.
