沉渣对钻孔灌注桩承载力影响分析

Analysis of bearing capacity of bored pile with sediments

通过大型有限元分析软件ADINA对桩体进行二维模拟,并采用大型数值分析软件MATLAB对得出的数据进行拟合,得出相应的经验公式,进而研究不同桩底沉渣厚度对钻孔灌注桩承载力的影响,具有一定的工程应用价值。

The paper undertakes the two-dimension simulation of piles by adopting ADINA, the large-scale finite element analysis software, a- dopts MATLAB, the large-scale numeric analysis software to fit the obtained data, achieves respective empirical formula, and researches the in- fluence of various thickness of sediments at pile bottom, so it has certain engineering application value.
