本文在前人对单排抗滑桩土拱效应和合理桩间距研究成果的基础上,对抗滑桩桩间土拱的成拱机理进行了简要阐述,结合土拱自身受力及变形特点,利用数值模拟的方法对合理桩间距条件下单排抗滑桩土拱效应的空间分布规律进行了研究。通过分析土体的应力及位移情况,发现土拱在不同高度条件下的分布是不同的,同时呈现一定的规律性。并且通过研究表明土拱具有一定的自身调节能力,以适应不同滑坡推力的作用。
Based on the previous research results of arching effect and reasonable spacing of single pile anti-slide pile, the arching mechanism of soil arching between anti-sliding pile is briefly described. Combined with the characteristics of soil arching and deformation, The numerical simulation method is used to study the spatial distribution of soil arching effect of single-row anti-slide piles under reasonable pile spacing conditions. By analyzing the stress and displacement of soils, it is found that the distribution of soil arches is different under different height conditions, and at the same time shows a certain regularity. And through the study shows that soil arches have some self-regulating ability to adapt to the role of different landslide thrust.
