资兴高速顺谷岭隧道出口古滑坡分析与治理

An Analysis and Treatment of the Ancient Landslide at the Exit of the ShunGuLing Tunnel ZiXing Expressway

通过分析古滑坡对公路工程的影响和危害性,说明对其进行正确判断和分析的重要性。查明资兴高速顺古岭隧道出口古滑坡的地质概况,分析出古滑坡滑动的原因。对滑动面抗剪强度取值进行了室内试验和反算,并对古滑坡进行稳定性分析,确定采用抗滑桩结合抗滑挡土墙的综合治理措施。

This paper analyzes the influence and harm of ancient landslide on Expressway engineering to explain the importance of COtTect judgment. It makes an analysis of the geologic profile of the ancient landslide at the exit of Shun GuLing and Tunnel ZiXing Explressway, by analyzing the causes of the sliding of the ancient land slide. The indoor test and countenneasmre of the shear strength of the sliding surface wetre carried out. We have also analyzed the stability of the ancient landslide. The comprehensive control measures of slide-resistant pile combined with slide-tresistant tretaining wall atre determined.
