黑林观音滑坡成因机制及防治研究

针对某铁厂互通E匝道开挖路堑已形成的六级台阶及其支挡格构破损状态特点，依托黑林观音滑坡，结合邻近区域地灾态势，探索地质构造成因，确定岩层岩性特征，分析滑坡机制，摸清滑坡成因，并确认滑坡变形破坏机制的基本岩土力学模式。基于天然工况与饱和工况，运用FLAC3D建立该滑坡地质模型，分析黑林观音滑坡体位移变量和稳定程度，设计适宜的支挡方案。实施后，滑坡体已处于稳定状态。

Research on Formation Mechanism and Prevention of Heilin Guanyin Landslide

Aiming at the six steps formed in the excavation cutting of the interconnecting E-ramp in the iron works and the damage state characteristics of the retaining structure, relying on Heilin Guanyin landslide, combining with the features of geological disaster in adjacent areas, the genesis of geological structure is explored and the lithological characteristics of rock strata is determined to analyze the mechanism of landslide and found out the cause of landslide, and then confirm the basic geomechanical model of landslide deformation and failure mechanism. Based on the natural condition and the saturation condition, the geological model of the landslide is established by FLAC3D, the displacement and stability of Heilin Guanyin landslide are analyzed and the most suitable retaining scheme is designed. After the implementation, the landslide has been in a stable state at present.
