摘要
结合两例不同桩体刚度的工程实例——石灰搅拌桩和CFG桩复合地基,进行了室内试验和非线性有限元分析,探讨了柔性桩复合地基和半刚性桩复合地基受力、变形性能的不同所在。同时,通过现场载荷试验,验证了数值分析方法的可靠性和地基土本构模型选取的合理性。
Based on laboratory tests and nonlinear finite element analysis in two pratical projects,this paper discussed the difference between bearing and deformations performance of soft pile compound foundation and semi-rigid pile compound foundation for reference.
