摘　　要：针对长距离管道输水工程的事故停泵时管道瞬变流水击计算模型,采用拉丁超立方抽样法抽取样本参数,基于偏相关分析法进行全局敏感性分析,探究了模型参数间的相关性,增强了对模型参数的识别和理解。结果表明:对于最大水击压力,管道直径、泵后阀关阀时间、管道输水流量是灵敏度较高的3个参数。Based on Latin hypercube sampling and partial correlation analysis method,the global sensitivity of transient fluid water hammer calculation model in long distance pump water delivery project was analyzed.The results show that in the model of the project,the diameter of the main pipeline,the close time after the pump and the delivery flow in the main pipeline are the top three factors in sequence.
