摘　　要：结合土拱自身受力即变形特点,利用数值模拟的方法对梅花型布置双排抗滑桩土拱效应的空间分布进行了研究。通过分析不同桩位下土体的应力及位移情况,得到不同桩位所对应产生的土拱效应,而土拱效应的不同会使抗滑桩产生差别较大的支挡效果。发现存在合理桩位使相邻前后排抗滑桩之间形成直接土拱,进而能够充分发挥抗滑桩的阻滑性能。同时对合理桩位时的梅花型布置双排抗滑桩土拱效应沿桩长方向的分布规律进行了研究,并对结果进行了归纳总结。Combined with characteristics of the soil arch deformation and the force,the spatial distribution of soil arch effect of quincuncial layout double-row anti-slide pile are studied by using the method of numerical simulation. By analyzing the stress and displacement of soil of different pile location,the soil arch effect corresponding to different pile location are acquired,and the different soil arch effect causes larger difference retaining effect of pile. There is a reasonable pile location,which existing between adjacent front and back piles,to form the directly soil arch which can give full play to the retaining effect of the pile. As well as the soil arch effect of quincuncial layout double-row anti-slide pile along the direction of the pile length is studied,and the results are summarized.
