摘　　要：对于单一管道的单相液体水击现象计算已经比较成熟,但是很少有对于复合管道的液固两相流系统的浆体水击 计算方面的报道。根据实际工程设计需要,提出了具有复合管道的液-固两相流浆体水击压强的计算方法。同时对某电厂 液一固两相流输灰系统浆体水击压强进行了计算与分析,提出了防止浆体水击的措施。The calculation of water- hammer pressure phenomenon of single- phase liquid is already more mature for a pipeline of uniform characteristics, but the less work has addressed the calculation of slurry water hammer pressure in complex pipelines with slurry flows carrying solid particles. This paper has present calculation methods of slurry water-hammer pressure on liquid-solid two-phase flow system in complex pipelines for actual engineering design. At the same time the calculation and analysis of slurry water-hammer pressure on liquid-solid two-phase flow systems has been done for a steam power plant. Measures to reduce water-hammer pressure in pipelines with slurry flows carrying solid particles are presented.
