| Abstract: | By analyzing the prototype observation data for the double layer outlets of Sanmenxia dam, in this paper, the following hydraulic problems found through hydraulic model tests, on which identical agreements was not reached, were clarified: what is the nature of the bow-shape vortex band within the inlet inclined gate slot; if the cavitation in the top corner area can be eliminated or not after the modification of the inclined gate slot; if cavitation problems is in existence at the position of connection well. The results have practice significance on the schedule of the modification of the outlets. |

| Keywords: | cavitation noises non-cavitation noises vortex cavitation band non-cavitatjon vortex band. |
