A Study on Factors Affecting Energy Dissipation of Orifice Tunnels of Xiaolangdi Project

Xiaolangdi Project rebuilds the conversion of diversion tunnels into the orifice tunnels for energy dissipation, which resolves the complex technical problems of high heads and velocities resulted from the conversion. This article introduces energy dissipation conditions of orifice tunnels and several main factors which affect energy dissipation.
