不同材料桩型时的桩基三维有限元分析
摘要:近年来,以控制差异沉降为目标的桩基础变刚度调平方法在我国岩土工程界受到越来越多的重视和应用。用三维有限元方法研究在同一基础下采用不同桩型情况时各桩沉降和刚度的关系,探讨通过改变桩型来调整刚度,最后控制差异沉降的方法,并通过工程实例阐述运用不同桩型进行设计的概念和方法,达到减小差异沉降。
Abstract:Recently more and more attentions are given to the variable rigidity design method for controlling differential settlement, The three dimensional(3-D)finite element method is used to discuss the relation between settlement and rigidity of foundation supported by different type piles.A design method is presented to control differential settlement by changing types of piles and layout of piles.A case study shows that this method can be used to reduce the differential settlement and prevent second stress.
