摘要
以数值方法为工具,建立长短桩复合地基的计算模型,探索了长短桩复合地基桩土相互作用的机理、荷载传递的性状及附加应力分布的规律,为群桩复合地基的优化设计提供了理论基础。
Based on the unique advantages of numerical test,the bearing mechanism and the distribution pattern of the additional stresses of the longshortpile composite foundation with different pilestiffness are studied.Some useful conclusions are obtained for the further research and design.
