摘要
经过模型试验发现上郊水库溢洪道的原设计在进口段和急流弯道段的流速分布很不均匀,流态十分紊乱,造成不平衡的压力分布,给工程的安全带来威胁。在试验过程中对原设计方案进行了修改,从而改善了水流流态。
By means of hydraulic model test,it is dicovered that according to the original design of Shangjiao Reservoir＇s spillway,the distribution of velocity in inlet section and bend section of supercritical flow is very nouniformed,the flow pattern is confused,and the pressure distribution is out of banlance. All of these constitute menace to the security of engineering. In the process of test the spillway scheme is modified and the flow pattern of spillway is improved.
