某隧道进口仰坡滑坡机理及治理措施研究

以云南省某高速公路隧道进口仰坡滑坡为研究对象，通过地质调绘、钻探、物探、室内试验等综合勘察方法，查明滑坡的地貌特征、变形迹象、滑坡规模、滑坡物质组成和滑动面特征；结合深层位移监测曲线和滑坡所处的地质环境条件，进行变形破坏机理和稳定性分析，并采取相应工程处治措施。

Study on Mechanism and Control Measures of Front Slope Landslide at the Entrance of a Tunnel

Taking an front slope landslide at the entrance of an expressway tunnel in Yunnan Province as the research object, the geomorphic features, deformation signs, landslide scale, material composition and sliding surface characteristics of the landslide was found out by means of mapping, drilling, geophysical prospecting and laboratory tests. The deformation and failure mechanism and the stabilityof the landslide was analyzed combining with the deep displacement monitoring curve and the geological environment conditions of the landslide, and the corrsponding engineering treatment measures were taken.
