Abstract

HYDRAULIC JUMP STILLING BASINs are among energy dissipators which commonly designed at the downstream of spillways, chutes and sluice gates. The slab of the structure is effected by the HYDROSTATIC PRESSURE and uplift pressure in which during operation fluctuate. Therefore the effect of pressure fluctuation is an important aspect of slab design in which have not been considered in the past. In this study an extensive experimental program have been conducted to clearly define new design criteria. The experimental set-up consisted of a flume 20.0m long, 0.9m width. Tests were performed at the downstream of ogee spillway l.2m height. Six different discharges ranged from 30 to 170 lit/sec applied to produce different discharges numbers ranged from 5 to 12. For each test, the pressure fluctuation was recorded every 30 second resulted 108000 data. To determine the criteria for slab stability, three slabs in different sizes made of concrete were installed in the test section and each slab was tested under different hydraulic conditions. Applying the DIMENSIONAL ANALYSIS, a general relation was developed. Using this relation and experimental data a formula was developed to be applicable for the design of slab at the base of HYDRAULIC JUMP STILLING BASINs. The experimental program and results are presented. A comparison of the new method with previous method is presented also.
