摘要
抗滑桩加固边坡具有较好的效果,基于ABAQUS数值计算软件,采用强度折减法,研究桩位、桩间距与桩径比、桩长等因素对边坡安全系数以及边坡失稳时滑裂面出现位置的影响。研究表明,安全系数随桩间距和S/B的增大而减小;最优加固位置L_x/L=0.2~0.4处,综合边坡加固效果最佳;抗滑桩长度在22~26 m较为合适,抗滑桩的锚固深度为4/11~5/13桩长较为合理。
The anti-sliding pile reinforcement slope has a good effect. Based on the ABAQUS numerical calculation software,the strength reduction method is used to study the factors such as pile position,pile spacing and pile diameter ratio,pile length and other factors on the slope safety factor and slope slippage. The influence of the location of fracture surface,the study shows that： the safety factor decreases with the increase of pile spacing and S/B; The optimal reinforcement position L_x/L = 0. 2 - 0. 4,,the comprehensive slope reinforcement effect is the best; the length of anti-slide pile is suitable for 22 - 26 m. The anchoring depth of anti-slide piles is 4/11 - 5/13 and the length is reasonable.
