斯木塔斯水电站台阶式溢洪道消能设计

Simutasi Hydropower Station Step Spillway Energy Dissipation Design

新疆斯木塔斯水电站台阶式溢洪道的模型试验表明:台阶溢流面有较好的消能效果,其消能率与台阶尺寸、单宽流量等因素有关,在小流量的情况下,消能率可达到80%以上,对下游冲坑深度也有所降低。本文对此加以介绍。

Model test of Xinjiang Simutasi hydropower station step spillway showed that： the step over-flow surface has excellent energy dissipation effect; its energy dissipation rate is related with step size, single-wide traffic and other factors. The elimination energy rate can reach 80% or higher in the case of small flow. The downstream scour depth is also decreased. The condition is introduced in the paper.
