丰满水电站重建工程泄洪消能建筑物地基岩体抗冲刷流速选取与冲刷坑深度估算

摘要

泄洪消能建筑物基础岩体抗冲刷流速值的准确性十分重要, 如果地质建议值偏低, 则水工模型试验冲刷深度偏大, 增加工程投资, 影响工程进度. 丰满水电站重建工程采用工程类比与计算相结合的方法,为设计提供了合理的抗冲刷流速建议值, 并估算了冲刷坑深度.%The accuracy of the scouring velocity value of rock foundation in the building used to discharge flood energy dissipation is very important .If the geological suggestion value is low ,the test scour depth of hydraulic model is larger , which will make the engineering investment high and affect the construction schedule .The paper combined engineering a-nalogy with calculation method in the reconstruction of Fengman Hydropower Station .This provides a reasonable scouring velocity value ,and estimates the depth of the pit .
