摘要
瓯飞一期围垦工程东2#闸为低水头水闸,属于低佛氏数消能;闸下为淤泥,起动流速很低,极易被冲刷。原设计方案模型试验表明,常规消能布置形式存在基础开挖困难、堤脚盘头冲刷严重、防冲槽维护费用高等缺点。通过对东2#闸常规消能布置形式与新型消能布置形式的对比试验,推荐新型闸下消能布置形式。
East 2 # Brake in the tirst phrase of Oufei reclamation project is a low head sluice, which belongs to low froude numi^r of energy dissipation. Under the brake is mud, and starting velocity is low, causing mud to be. washed easily. The original design of the model tests show that there are many shortcomings in conventional energy dissipation arrangement, such as foundation e^cavation dimcuh, serious scour of disk - shaped dike, high anti - punching maintenance cost, etc... Through the comparison test between conventional and new energy dissipation arrangement of East 2 # Brake, this paper recommends the new energy dissipation an＇angement under the brake.
