| 摘 要： | 为了保证马来西亚沐胶电厂的冷却取水安全,需要研究解决蓄水池的泥沙淤积、清淤频率、冷却水的泥沙含量和粒径,以及引水通道过流能力等一系列泥沙问题。本文首先采用基于非均匀不平衡输沙数学模型对蓄水池的泥沙淤积问题进行了研究,给出了淤积量、淤积沿程分布、冷却水的含沙量和泥沙粒径,对蓄水池清淤频率提出了建议。针对电厂冷却蓄水池引水通道Bedengan河道的过水能力不足问题,提出了以展宽为主和以挖深为主的两种改造方案,给出了改造后的Bedengan河道的断面形态、底标高、底宽等设计参数。研究成果解决了沐胶电厂的工程泥沙问题,对保障电厂运行和冷却用水安全有重要实际意义。

| Abstract: | To insure the safe operation of the Mukah Power Plant,the sea water should be diverted through the Bedengan River to cool the power generation machine.However,the power plant has to face two problems.One is the insufficient flow-conveying capacity of the Bedengan River and the other is the sedimentation in the cooling water tank.Based on non-uniform sediment transport and hydraulics theories,the two issues have been investigated.The results show that the deposition ratio of sediment in the cooling water tan... |
