高尾矿坝塔式进口竖井排洪道的泄流能力

Discharge Capacity of Shaft Spillway with Framed Inlet Tower for High Tailings Dam

介绍了用于高尾矿坝的具有圆形框架式进水塔的竖井排洪道泄流能力模型试验研究。基于大量试验实测资料，考查了影响泄流能力的几何边界条件和水力因素，给出了这种排洪道以环形堰流、孔流、孔堰多层流以及有压管流等各种流态运行时泄流能力计算公式．

Abstract The discharge capacity of shaft spillway with framed inlet tower used for high tailings dam is studied by physical model. According to the model tests and measured data,the boundary conditions and the hydraulic factors affecting discharge capacity are analyzed. By means of statistical analysis,a series of formulae to calculate discharge capacity of flow pattern such as ring weir now,ring orifice flow,multiple-layer flow of ring weir and ring orifices and pressure pipe flow are proposed.
