In the ice-cut,especially in fierce ice-cut process of seasonal frozen river,hydraulic structures,such as dykes and revetments,are suffering large-scale ice flow.This may lead to ice jam and even ice dam,which would increase the risk of rise in water level,floodplain,dyke breaching and loss of properties.To explore the law of evolution of ice flow and prevent the disaster of ice flow,we propose the prototypical experiment method of ice flow evolution and carry out prototypical experiment of ice flow evolution in the stream segment of Tangyuan River in Songhua River.By RTK equipment,the path of various model particles and collision to revetments are recorded.With reference of native wind velocity data,the influence of flow field,wind velocity,and waterway topography to ice flow movement are analyzed;the factors of ice flow’s collision to revetments and possible destruction position and forms are obtained.This paper provides theoretical reference on the formation mechanism of ice jam and ice dam,and gives a guidance to dyke arrangement and reinforcement.
