Test on the Shape Schemes of Jilintai-I Hydropower Station Flood Discharge System
According to the original scheme, the surface spillway tunnel of the Jilintai-I hydropower station flood discharge system was designed to be arranged separately, but not to be combined with diversion tunnel; the radial gate of the lower level spillway tunnel was designed not to have the vertical drop and lateral sudden enlargement, and the discharge structures at oblique tunnel were designed to be cancelled. In this paper, through the test on the hydraulic model, the analysis on the test results and many advisory demonstrations, multiple modifications and optimizations are made for the shape design of the axis, bottom slope and local structure of bottom slope and local structure, and also an analysis is conducted on the test results of the main shape scheme of surface spillway tunnel, and then the related opinions and suggestions are proposed according to the existing problems. The way of the pressured vertical drop and lateral sudden enlargement was ultimately used in lower level spillway tunnel of the hydropower station flood discharge system. Also, in this paper, the author makes a hydraulic test on the main shape design of lower level spillway tunnel based on the original scheme, and then an analysis is conducted on the test results and a final scheme is proposed according to the actual problems.
