摘　　要：分析堰塞湖特大型崩塌的发生过程认为,山坡上部白云质灰岩节理裂隙发育,下部不整合接触砂泥岩含软弱夹层。在此构造和节理条件下,受强风化作用和地下水入渗,斜坡后缘拉张开裂,前缘压缩弯曲。受地震诱发形成此特大型崩塌。An analysis was made of the formation of the collapse that had formed Hong shiyan Quake Lake after Ludian Earthquake on Augst 3, 2014. The results show the upper dolomitic limestone is full of joints and fissures, and the lower sand mudstone is of contact unconformity with weak interlayers. The slope cracked at the back and bent at the front with strong weathering and infiltration of groundwater. And the earthquake triggered the col lapse.
