The stability of the barrier lake in the Guxi River in Yushan,Xinjiang caused by"1·23"earthquake
Affected by the January 24 earthquake in Aheqi County,Xinjiang,a barrier lake appeared in the channel of the Gushi River in Yushan due to the collapse of its banks.In order to explore the scale of the barrier lake and analyze the safety and stability of the barrier lake,this paper makes a comprehensive analysis based on the aerial survey data and the relevant norms.According to the current situation,the permeability coefficient of the simulated weir body is reversed,the preliminary conclusion is obtained by the geological analysis of the weir body and weir lake,and the calculation and analysis of the seepage stability of the weir body is obtained.The risk of dam failure in full section is low.The research results of this paper provide a theoretical basis for the protection emergency plan of the buildings in the lower reaches of the Guxi River quake lake in Yushan,Aheqi County and its adjacent affected areas.
