鹰嘴岩崩塌体为典型的逆向岩层崩塌，属于拉裂式崩塌，该崩塌的形成受地形地貌、地层岩性、地质构造、大气降雨等因素的控制。由于崩塌体上部岩层和下部岩层坚硬，中间存在软弱夹层，构成了三明治式的地层岩性组合形式，这种地层岩性组合是造成鹰嘴岩崩塌体失稳的重要因素，另外，当大气降雨渗入危岩体裂隙，加速了崩塌的发生。本文对鹰嘴岩崩塌体地质环境条件及该崩塌体的成因机理进行分析，结果表明鹰嘴岩崩塌体目前处于不稳定状态，随着现存危岩体上裂缝的不断发展变化，鹰嘴岩崩塌体有再次发生崩塌的危险。

Yingzuiyan collapse is a typical reverse strata collapse, belongs to ripping-type collapse, and formation of which is under the control of terrain geomorphology, lithology, geological structure, rainfall and other factors. Upper-part and under-part of the collapse are composing of rigid rocks, while the middle-part has got a weak layer, which makes a sandwich-type lithology combination. This type of rock structure is the key factor influence the stability of Yingzuiyan collapse, while the infiltration of rainfall to the rock mass fissures accelerated the collapse occurred. Geological environment conditions and genetic mechanism analysis of Yinzuiyan collapse indicated that the collapse body is in an unstable state, with the evolving cracks in the existing dangerous rocks mass, the next landslip may happen in the near future.
