Abstract

This paper aims at the complicated flow pattern of non-pressure spillway tunnel during operation. Based on the reconstruction project of Qingshan Reservoir spillway tunnel, this paper makes a mathematical derivation of the calculation and analysis of the constant gradient flow surface line of rectangular section in the non-pressure spillway tunnel, and gives the analytical solution between the flow S and the beginning and end water depth. It is more simple and convenient than the standard recommended piecewise trial algorithm. Finally, through the comparative analysis of 1:30 hydraulic model test results of Qingshan Reservoir spillway tunnel reconstruction project, it is considered that the analytical solution of water surface line calculation proposed in this paper is reasonable and reliable. It provides a basis for ensuring flood safety of spillway channel and downstream river, and can be used as reference for similar projects.
