摘　　要：本文对复杂泵系统水锤数学模型进行了分析与推导 ,建立了带盲管的多台并联泵向不同阻力特性的多管道供水的水锤计算方程组并对该非线性双曲方程进行了求解 ,对该系统三次水锤事故进行了模拟计算 ,找出了三次事故的原因。In this paper, the mathematic model of water hammer under the complex pump system is analyzed and a water hammer calculation equation is established. This equation is under the following conditions: water supply from multiple pumps in parallel with a blind pipe to the multiple pipes with different resistance characters. Authors also gave a solution of the non linear doublecurve equation. There 3 accidents of water hammer have happened in this system. Authors made an analogy calculation of these accidents, and the causes of accidents are analyzed.
