摘要
通过计算黑水县俄瓜热十多沟泥石流运动参数,分析震后泥石流运动与堵溃特征、成因,为合理选择治理方案提供依据.计算表明,主沟流速为4.2~9.4m/s,峰值流量279.55m^3/s.该区域泥石流发生的主要成因由于泥石流流通过程中发生堵溃,堵溃之后泥石流流量急剧增加,具有迅速扩大效应.针对该沟泥石流现状,提出了合理的治理方案,并达到了预期的治理效果.
By calculating the movement parameters of debris flow in Kgua Reshiduo ditch Heishui County,the characteristics and causes of debris flow movement and blockage arc analyzed,which provides a basis for rational selection of control schemes.The flow velocity in the main gully is 4.2~9.4 m/s,and the peak flow is 279.55 m^3/s.At the same time,the main cause of the debris flow is that the flow of the debris flow increases sharply due to the blockage in the process of debris flow circulation.In view of the current situation of debris flow,reasonable measures and schemes are put forward and the expected control effect is achieved.
