Dumping Materials for Reducing the Difficulty of River Closure and Dike Protection
摘要
Abstract
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.关键词
