长距离浆体管道输送操作过程中会发生水击现象，严重影响系统运行的安全性和可靠性。关阀水击在管道操作过程中普遍存在。为通过模型计算，有效预测关阀水击压力，文中综合考虑了浆体特性对水击波速的影响，采用弹性水击理论，应用水击连锁方程得到浆体管道关阀水击压强模型。通过实验室实测数据与模型对比，验证了该模型数据与实测数据误差较小。
長距離漿體管道輸送操作過程中會髮生水擊現象，嚴重影響繫統運行的安全性和可靠性。關閥水擊在管道操作過程中普遍存在。為通過模型計算，有效預測關閥水擊壓力，文中綜閤攷慮瞭漿體特性對水擊波速的影響，採用彈性水擊理論，應用水擊連鎖方程得到漿體管道關閥水擊壓彊模型。通過實驗室實測數據與模型對比，驗證瞭該模型數據與實測數據誤差較小。

Water hammer happened in long-distance slurry pipeline transportation and it will severely influence safety and reliability of the system. The water hammer of closing valve occurs frequently. In order to forecast water hammer pressure of clos-ing valve by formula,the influence of the characters of slurry on wave speed was considered in this article. According to elasticity theory and interlocking equation of water hammer,water hammer model of slurry was deduced. The result shows that there is little difference between the modeling data and the measured data.
