高速公路边坡抗滑桩加固分析

Reinforcement analysis of anti-slide piles on expressway slope

基于霍永高速公路高边坡处治实践,对抗滑桩加固效果进行分析。根据施工现场调查结果,制定方案采用抗滑桩对边坡进行加固处理。布置测点对表面位移开展监测,分析监测结果得出桩顶位移和坡面位移总变形量均较小,且在抗滑桩完工后得到了有效控制。分析深部位移监测结果,得出随深度增加抗滑桩变形呈现先增大后减小的趋势,监测结束后变形基本趋于稳定,说明抗滑桩有效控制了边坡滑动,加固效果明显。

Based on the practice of high slope treatment of Huo-Yong Expressway,the effect of anti-slide pile reinforcement is analyzed.According to the survey results of the construction site,a plan was formulated to use anti-slide piles to reinforce the slope.The measurement points are arranged to monitor the surface displacement.Analysis of the monitoring results shows that the pile top displacement and the total deformation of the slope displacement are small,and they are effectively controlled after the completion of the anti-slide pile.Analyzing the results of deep displacement monitoring,it is concluded that the deformation of the anti-slide pile first increases and then decreases as the depth increases.After the monitoring,the deformation basically stabilizes,indicating that the anti-slide pile effectively controls the slope sliding and the reinforcement effect is obvious.
