| Abstract: | Tail-flaring pier stilling pool " is an energy dissipation method first put forward by China 30 years ago. Based on model test results and the synthetic analysis of flow fluctuation load testing data for great quantity of points and areas, the distribution of hydrodynamic pressure on stilling pool base slab under jet flow from tail-flaring pier is generally drawn out, the selection principle and point, area fluctuation load factors are put forward, which not only provide a scientific basis for the Baise stilling pool base slab structural stability calculation, but also enrich our knowledge on the flow dynamic characteristics of this energy dissipation method. |
