Submersible-Type Tainter Gate for Spillway Marseilles Lock and Dam: Hydraulic Model Investigation
A 1:20-scale hydraulic model simulated a 120-ft-wide section of the spillway and stilling basin including one freely suspended 60-ft-wide by 16-ft-high submersible tainter gate. The gate lifting mechanism consisted of a cable at each end of the gate attached to load cells. The magnitude and frequency of the forces acting on the cable supporting each end of the gate were measured. Tests indicated that there was a likelihood of the cables being subjected to exciting forces occurring at a random frequency with flow (a) over and (b) under the subject gate. The magnitude of these forces was about 1 percent of the total gate weight. Discharge characteristics and coefficients and stilling basin performance with various operating scenarios were determined. Keywords: Hydraulic forces, Submersible gates, Spillway, F Vibrations. (aw)
