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。
Using numerical method as a tool, the calculation model of long-short piles composite foundation is established. The mechanism of pile-soil interaction, the characteristics of load transfer and the rules of additional stress distribution are explored. The theory is provided for the optimal design of pile group composite foundation basis.
