摘要
基于数值模拟方法,分析研究了抗滑桩桩间距、滑体抗剪强度指标、滑坡推力对土拱效应的影响。结果表明,通过土拱效应作用在桩上的土压力,随桩距增大先增大后趋于平稳,随抗剪强度指标增大先增大后减小并趋于稳定,与滑坡推力增大成正比。
Based on the numerical simulation method,this paper analyzes and studies the influence of anti-slide pile spacing,slide shear strength indix and landslide thrust on soil arching effect.The results show that the soil pressure acting on the pile by the soil arching effect tends to be stable with the increase of the pile distance,and first increases then decreases with the increase of the shear strength index,which is proportional to the increase of the landslide thrust.
