山区高速公路高边坡滑坡治理方案研究

Research on High Slope Landslide Treatment Scheme of Expressways in Mountain Area

摘要:

为探讨山区高速公路高边坡滑坡治理合理方案选择，以贵州省道新高速公路某高边坡滑塌为据，依据工程地质条件与边坡自身稳定状态，分析边坡滑塌产生的原因，采用不平衡推力法对边坡稳定性进行验算。根据验算结果提出采用抗滑桩配预应力锚索的方式进行边坡加固，并阐述加固施工方法。对抗滑桩桩顶位移进行监测，数据表明加固效果良好，能够有效治理边坡下滑，保证工程安全。

Abstract:

In order to discuss the rational scheme selection of high slope landslide treatment of expressways in mountainous area, taking a high slope landslide of the new expressway in Guizhou Province as an example, according to the engineering geological conditions and the stability condition of the slope, the cause of the slope collapse is analyzed, and the unbalance thrust method is applied to check the slope stability. According to the results of the checking calculation, the anti-slide pile and the prestressed anchor cable method is proposed to carry out the slope reinforcement, and the reinforcing construction method is expounded. The top displacement of the anti-slide pile is monitored. The data shows that the reinforcement has the good effect, which can effectively treat the slope slide and ensure the safety of the project.
