For the first time, the connection between the formation of the ultra-high pressure ice dam on the Chuya-Kurai glacier-dammed lake and the development of aufeis processes on the Chuya river was substantiated. Consideration is given to the mechanisms of self-regulation in the process of glacier-dammed lake self-freezing as a consequence of a consequence of synchronous processes of Chuya river aufeis formation and the filling of the hollow with water. It is found that aufeis formation in sections of initial damming of the water flow caused an increase in the height and area of the dam and, hence, in its weight. Due to the large weight, favorable conditions were created for the development of the processes of regelation and plastic viscous flow of the monolithic ice massif, without formation of cracks and water flow channels inside the ice body. These factors were responsible for the long-term resistance of the dam to destruction processes. A possible retrospective assessment of the lake filling duration at different flow rates in the Chuya channel is made. It is established that the suggested formation mechanism for a high-pressure ice dam is consistent the well-known cryogenic-hydrophysical patterns and can, therefore, apply for realistic events.

冰坝的自我冻结：自我调节算法

首次证实了楚亚库赖冰川堰塞湖超高压冰坝的形成与楚亚河奥菲斯过程的发展之间的联系。考虑了楚雅河奥菲斯形成和空洞注水同步过程导致冰川堰塞湖自冻过程中的自我调节机制。研究发现，在水流初始筑坝部分形成的 aufeis 导致了大坝高度和面积的增加，从而导致了其重量的增加。由于重量大，为整体冰块的再凝胶化和塑性粘性流动过程的发展创造了有利条件，而不会在冰体内部形成裂缝和水流通道。这些因素是造成大坝长期抵抗破坏过程的原因。对楚崖河道不同流速下的湖泊充填持续时间进行了可能的回顾性评估。已确定高压冰坝的建议形成机制与众所周知的低温水物理模式一致，因此可以应用于现实事件。
