摘要
采用有限元软件ANSYS9.0研究了被动桩中土拱效应的产生机理,分析了土体内摩擦角、粘聚力、桩间距等影响因素对土拱效应性态和桩土应力分担比的影响。得出桩间距是影响土拱效应的最主要因素的结果。
This paper studies the mechanism of soil arching effects in passive piles by applying finite element analysis software package, ANSYS9. 0, analyzes the effects of internal friction angle of soil, adhesive force of soil and pile spacing displacement on the behavior of soil arching effects and concludes that the ratio of pile spacing to pile diameter plays the most important role in soil arching effects.
