桩土相互作用研究综述

鉴于桩土相互作用研究在刚性桩复合地基理论研究中的意义,对国内外桩土相互作用研究现状进行了总结.介绍国内外桩土相互作用两大类研究方法———理论分析方法、试验方法各自的特点和适用范围,并分析了其各自存在的主要问题.指出接触面本构模型的完善、计算方法的改进、数值分析与试验相结合是桩土相互作用问题研究的发展方向.

Recent researches on soil-pile interaction

In consideration of the significance of soil-pile interaction(SPI) in the research of the theory of the rigid pile composite foundation,a summary is made on current researches on SPI at home and aboard.Two types of research methods for SPI,i.e.the theoretical analysis method and the experimental method,as well as their characteristics,applicability,and some related problems are reviewed.It is pointed out that the perfection of interface constitutive model,the improvement of computational method,and the combination of numerical analysis with experimental study are the trend of further research on SPI.
