Dynamic Loading on Sidewall Monoliths of a Spillway Stilling Basin: Hydraulic Model Investigation

摘要

Guidance for determining the magnitude of hydraulic forces acting on a stilling basin sidewall is presented. A designer knowing the unit discharge, spillway height, velocity entering the stilling basin, Froude number, sequent depth, and tailwater depth can compute the average hydraulic force and maximum pulsations for any increment of sidewall length. The maximum overturning moment about the base of any portion of the sidewall can also be determined. Appendix A presents an example problem illustrating the recommended application for estimating the magnitudes and locations of the resultant dynamic forces acting on a stilling basin sidewall.
