摘要：

基于非线性有限元方法,对平行布置与梅花型布置方式下双排抗滑桩的土拱效应进行了考察.对比计算表明,前排、后排抗滑桩均能产生土拱效应.平行布置情况下,后排桩桩间土体的土拱效应不显著;而梅花型布置方式有利于前排桩与后排桩共同产生土拱效应,其作用效果优于平行布置方式.进一步分析表明,前排与后排桩所承担的荷载比例不同,因此,在抗滑桩的设计过程中可根据各排抗滑桩的荷载设计相应强度,达到经济合理的效果.

Abstract:

Using the nonlinear finite element method, the influence of parallel and quincuncial layout styles on soil arching effect of double-row anti-slide piles has been studied. It is found that soil arching effect can occur at both the anterior pile and the posterior pile. The soil arching effect of anterior piles and posterior piles can occur easily and distinctly with the quincuncial layout style. It can also be found that the loading at anterior piles is remarkably heavier than that at posterior piles, which suggests that a more economic and reasonable design can be proposed for reducing the design strength of posterior piles.

Key words: anti-slide pile, pile spacing, layout style, soil arching effect
