【摘要】 在25个比例为1∶5的三桩承台试验模型的试验研究的基础上,深入研究了承台内部力流的传递机理,并与现行规范(CECS8897)引用的原理进行比较,指出三桩厚承台的传力机理并不符合厚板弯曲理论,结合有限元分析结果,探讨了三桩厚承台空间桁架模型的形式,提出了相应的计算方法。更多还原

【Abstract】 After the analysis of the failure mode of the experimental model on twenty-five thick pile caps with three piles,the study on the transfer mechanism of mechanic fluid in the thick pile cap was conduced. It pointed out that the defects of the transfer mechanism of thick piles cap with three piles do not accord with the blending law of the thick slab by comparing it with the law in specification for design of reinforced concrete pile caps (CECS 88:97).The results of finite element analysis were added. The principle of space truss model of thick pile cap with three piles is proposed.更多还原
