长短桩组合桩基础的弹塑性分析

摘要

长短桩组合桩基础是一种新型基础形式,通过考虑桩土接触非线性对进行长短桩组合桩基础弹塑性分析,研究在组合荷载作用下的长短桩承载能力,揭示长短桩联合工作机理,对今后此新型结构设计提供理论支持.%The design method of long-short combined pile foundation has been concerned by the civil engineers. Based on pile-soil non-linear contact,an three-dimensional elastoplasticity analysis on the long-short combined pile foundation was conducted to study the bearing Capacity of the foundation under complex load. The work performance mechanics of combined pile foundation is revealed. The research conclusion can provide a theoretical support for this newtype structure design in the future.
