Application of Roughening with the Grass Cushions in the Hydraulic Model of Comprehensive Harness of Qian'an Reach of Luan River

Abstract:

Restricted by such factors as the size of test area, amount of work and water depth of model, hydraulic models are often made into distorted patterns, whereas the distorted models demand for roughening usually. The hydraulic model of comprehensive harness of Qian'an Reach of Luan River requires big roughness that general roughening technologies cant meet, so the plastic grass cushions were introduced. The preliminary experiment in flume, the preliminary experiment of the comprehensive model and the verification experiment of the comprehensive model proved the feasibility of the technology of roughening with the grass cushions in hydraulic model tests.
