【摘要】 通过大型通用有限元程序ANSYS建立模型,研究了复合地基和天然地基在地震作用下的附加沉降,计算结果表明,采用复合地基技术,对减少附加沉降有很好的效果。同时对群桩复合地基不同桩位特点进行分析,表明群桩复合地基中桩附加沉降大于边、角桩。提出了附加沉降系数的概念及计算公式,可对复合地基的设计提供技术支持。更多还原

【Abstract】 ANSYS code is used to study the settlement of composite foundation and natural foundation under earthquake action.The results show that the composite foundation has better effect than natural foundation.In the meantime,the pile group composite foundation is studied further in different pile positions.The settlement coefficient and its calculation formula are put forward.They contribute to the design of composite foundation.更多还原
