摘　　要：优化抛投物料的性状、选择实用性好的抛投材料是降低截流难度的措施之一。根据圆柱体的物理特性分析和截流水工模型试验成果,顺坡面抛投圆柱线体材料截流,材料可一次滚入龙口深槽,且在水下稳定性好。抛投圆柱线体材料截流可保护戗堤坍塌、阻止截流材料流失。在节省材料、制作、存放、运输等方面圆柱形体材料也具有明显的优点。圆柱线体抛投材料还可在江河堤防、水库大坝紧急抢筑、支护中发挥作用。To select applicable dumping materials and optimize their performance is one of the measures of reducing the difficulty of river closure.In light of the physical properties of cylindrical material and hydraulic model tests of river closure,the cylindrical wire materials are dumped along the slope surface,rolling down to the deep trough of the closure gap easily and remaining quite stable underwater.Cylindrical wire dumping material proves to be capable of protecting the closure dike from collapsing and preventing river closure materials from losing.Moreover,it has apparent advantages in terms of material saving,production,storage and transportation.It is also presented that cylindrical wire dumping material can be used in the emergent construction and supporting of river embankments and dams.
