【摘要】 通过对于高度一定的柱下独立四桩承台的ANSYS有限元计算分析,得出四桩厚承台的空间桁架传力模式及斜压杆的劈裂或压碎破坏机理。并且比较在相同配筋率下,不同配筋形式;相同配筋形式下,不同配筋率;及腹部配置水平钢筋网对承台极限承载力的影响。研究成果有望降低承台的厚度,从而降低承台工程造价,赢得行业宏观经济效应。更多还原

【Abstract】 This paper validates the load transfer mode and failure mechanism through the nonlinear finite element analysis of thick four-pile caps,and compares the bearing capacity of pile caps between different forms of reinforcement under the same reinforcement ratio and different reinforcement ratio under the same form of reinforcement and studies the punching bearing capacity of pile caps with belly horizontal mat reinforcement. It is thus hopeful that the thickness of pile caps could be reduced,and so do the engineering costs of the pile caps.更多还原
