软弱土质道路边坡抗滑桩加固分析

Analysis of Stabilization of Anti-sliding Piles on Soft Soil Road Slope

近几年来,在甘肃等偏远地区大量修建高速公路,以此来推动偏远穷困地区经济发展,在这些地区修建道路的过程中,容易遇到边坡软弱土质问题,道路边坡经常出现滑坡问题,土质状况复杂多样,所以必须对软弱土质道路边坡进行抗滑桩加固,在部分滑裂面确定最优加固位置,根据抗滑桩剪力以及弯矩分布情况合理设计抗滑桩桩长,才能充分发挥抗滑桩加固的作用,确保软弱土质道路边坡保持稳定。基于此,本文对软弱土质道路边坡抗滑桩加固施工技术进行了深入分析,并提出了一些建议。

In recent years, a large number of expressways have been built in remote areas such as Gansu to promote economic development in remote and impoverished areas. In the process of building roads in these areas, it is easy to encounter the problem of soft soil on slopes, and landslides often appear on road slopes. The problem is that the soil conditions are complex and diverse. Therefore, anti-slide pile reinforcement must be performed on the soft soil road slope, and the optimal reinforcement position must be determined in some of the sliding surfaces. The anti-sliding pile length should be reasonably designed based on the shear force of the anti-sliding pile and the distribution of bending moments. In order to fully play the role of anti-slide pile reinforcement, ensure that the soft soil road slope remains stable. Based on this, this paper analyzes the construction technology of anti-slide pile reinforcement for soft soil slopes and puts forward some suggestions.
