某高速公路滑坡稳定性评价及治理建议

Stability Evaluation and Control Suggestion of a Highway Landslide

山区高速公路通常会通过滑坡地段,由于路基的开挖及填筑,往往会导致滑坡复活,增加了高速公路建设成本。文中在野外地质地貌调查基础上,对位于某高速公路通过地段的滑坡基本特征进行研究,并对其在路基填筑前后不同工况下的稳定性进行评价。结果表明,路基填筑前滑坡处于稳定状态,而路基填筑后滑坡会发生复活,建议坡脚设置抗滑桩支挡,坡面采用浆砌片石防护,且需设置排水沟。

In the process of highway construction in mountainous area,the excavation and filling of the subgrade often leads to the resurrection of the landslide,which increases the cost of the highway construction.Based on field geological landform investigation,the basic characteristics of a highway landslide is analyzed,and the stability of the landslide is evaluated.The results show that the landslide will be resuscitated,and the slope protection by mortar rubble,the drainage ditch and the anti-slide pile are recommended.
