浅析某软岩路堑边坡治理
|
摘要
现有道路路堑边坡设计往往是根据经验,对于不同地质条件的边坡,没有进行具体分析,造成了边坡设计中的不合理。该文结合某高速公路开挖高陡路堑边坡病害治理工程实例,分析了该工程路堑边坡滑坡的特征,并进行了稳定性分析。结合已有工程治理措施提出了设置环形排水沟,维持原来的坡面防护结构,在第一级和第三级坡顶平台增设抗滑桩的治理方案。为类似路堑边坡治理取得了具有实际意义的工程治理经验。
The existing design of road cutting slope is usually based on experience,it has no specific analysis,for different geological conditions of the slope,which has caused that the design of the slope is not reasonable.Combining with the construction of some highway with slope treatment project as an example,the procedure of cutting slope managent was analyzed briefly.Based on the existing engineering management measures,the treatment plan was proposed.It provides a valuable reference to other similar landslide treatment projects.
