Calculation of strength of stilling basins and pressure in downstream water outlet structures

Abstract

Calculations performed to determine the strength of the stilling basin and apron of the downstream zone should mainly be carried out, considering the conditions of their stability and strength. When calculating the elements of the fastening zone for strength and stability, it is advisable to consider vertical and moment hydrodynamic stresses. Conducting targeted research on developing scientific methods for calculating the interface between the spillway and downstream outlet structures, mitigating kinetic energy in the downstream toe, choosing designs for protecting downstream of the structure, and determining hydrodynamic loads is particularly important. In this regard, one of the important tasks is to conduct scientific research on improving the design of the downstream toe, working out methods for determining hydrodynamic loads while calculating the thickness of the stilling basin and apron, which ensures the strength of the downstream toe.
