摘要
基于模型试验,本文研究了水垫塘透水底板的水动力特性。结果表明,与不透水底板相比,透水底板可以显著地减小上举力,从而可以提高底板的稳定性。文中阐述的开孔率k、孔径D等对水动力荷载影响的成果,可为水垫塘透水底板的设计提供参考。
Based on the model test, the characteristics of the uplifting force on the pervious slab in plunge pool are studied. Compared to impervious slab, the uplifting force is reduced obviously acting on the pervious slab. The relations between the pervious coefficient（k） and the diameter of holes（ D ） and uplifting force on the pervious slab are analyzed. These results provide the basis for the design of the pervious slabs.
