黄河上游龙羊峡刘家峡河段两岸岸坡形成了众多残留体积超过108 m3的古巨型滑坡，最大体积近30×108 m3，且大部分堵塞过黄河。但部分巨型滑坡至今未有学者进行科学研究，其中包括德恒隆滑坡和锁子滑坡。结合区域地质环境条件，通过对德恒隆锁子两个巨型滑坡基本特征和滑坡堵塞黄河的野外7个地质现象进行分析，并对德恒隆锁子滑坡形成机制进行初步探讨，认为德恒隆锁子滑坡为地震型滑坡，且形成原因与青藏高原8万 a 的构造期有密切关系。通过分析黄河沿岸堰塞湖湖相沉积，认为堰塞湖形成时间为8万 a 左右，这与德恒隆锁子滑坡的形成年代一致。因此德恒隆锁子滑坡在地震作用下触发并堵塞黄河。

Giant landslides (1 × 10 8 m 3 ) are common along the upper Yellow River from Longyang Gorge to Liujia Gorge . The largest one on record reached 30 × 108 m3 ,which had ever blocked and dammed the Yellow River .The study on the mechanism of giant landslides along the upper Yellow River would be important for construction engineering and countermeasures to prevent from any undesirable events .The author analyzed seven geological occurrences ,and concluded that Dehenglong landslide and Suozi landslide occurred during 70 80 ka .They were triggered by an earthquake and dammed up the Yellow River at that time . They had a close relationship with the tectonic movement in Qinghai Tibetan Plateau before ca .80 ka ,which is evidenced by the existence of the dammed lakes caused by Dehenglong Suozi landslides .
