閘壩式樞紐工程閘前導(dǎo)水墻體形優(yōu)化研究
[Abstract]:The boundary condition of sluice dam junction project suddenly shrinks from the reservoir area to the sluice chamber section, the single wide flow through the gate chamber is large, the water head is high, the water flow state is poor and the intermittent inspiratory vortex is easy to occur at the inlet of the sluice gate. In order to study and select reasonable hydraulic conditions such as water flow state, streamline distribution, surface velocity, swirl distribution and lateral water level difference at the inlet of sluice, a numerical simulation analysis method is used. This paper optimizes the layout scheme of sluice front water wall in a gate and dam type project, and verifies and analyzes it by physical model test. The results show that the optimization scheme can effectively improve the flow pattern of the inlet water flow, reduce the transverse velocity of the water flow in front of the sluice, and eliminate the intermittent suction vortex in the shape of the guiding wall of the narrow channel bed near the dam in front of the sluice.
