Abstract

This paper takes the spillway table hole curved working gate as the research object, uses the finite element method to determine the force of the water load on each part of the gate under the ordinary working condition, the seismic working condition and the opening and closing working condition, and solves the internal force of each build according to the calculation result, the calculation result shows that under the design head, the strength and stiffness of the spillway table hole curved working gate in the three working conditions meet the relevant requirements. It provides effective data support for the structural design of spillway table hole curved working gates in hydropower stations, providing a reliable basis and experience for rapid design and general standardisation.

Keywords: Spillway meter hole, arc gates, seismic conditions, opening and closing conditions, finite element analysis
