摘要
用荷载传递法分析单桩,在分层地基模型中引入了土的邓肯-张本构模型,以此为桩土间的联结方式计算桩土地基柔度矩阵,土中应力的求解用Mindlin应力解和Boussinesq应力解计算,最后计算了一个工程实例,结果证明本文方法是可行的.
Load transfer method is conducted herein to analyse single pile, and the solution of the stress in soil is based on Mindlin＇s solution and Boussinesq＇s solution. Duncan-chang model is applied to compute the flexible matrix of piled foundation. At last an engineering example is analyzed, and the result has shown good agreement.
