桩基的稳定性:理论和最新进展

STABILITY OF PILES:THEORIES AND RECENT PROGRESS

本文对桩基的稳定性分析的数学模型、分析计算方法以及离心机模拟试验的近期文献进行了一定的回顾.主要侧重于桩基的失稳模式和机理分析,包括基于Euler屈曲理论的桩基不稳定性、桩基的定向不稳定性、地震液化中桩基的不稳定性、桩基的动力不稳定性、桩基的后屈曲分析等.最后简单地提出了进一步需要开展的工作.

In the present paper, mathematical models, analyzing and calculating methods as well as centrifuge tests of stability analyses of piles have been reviewed. Attention is mainly paid to the modes of instability and the mechanism analysis, included the pile instability base on Euler buckling theory, directional instability of driven piles, pile instability during earthquake liquefaction, dynamic instability of piles and post-bucking analysis of piles. Finally, a further study is presented briefly.
