摘　　要：印尼芝拉扎三期扩建项目厂址直接面向印度洋,潮汐动力弱,波浪动力非常强,且存在明显的涌浪特征,外海波浪对滨海电厂水工结构的影响不容忽视,特别是取水泵房前池的水位波动。通过模型试验,研究了不同水位、波高和波周期条件下引水箱涵的透浪系数Kt,分析了引水箱涵透浪系数的影响因素。试验结果表明:引水箱涵透浪系数Kt主要取决于引水箱涵入口处的波浪周期T;波周期越大,透浪系数Kt越大。另外,将引水箱涵透浪系数结果应用至印尼芝拉扎三期扩建项目取水泵房前池的水位波动分析,为其取水口平面布置方案的确定和优化提供了科学依据。Phase Ⅲ of Cilacap CFSPP is located facing the Indian Ocean,where the tide is weak and the wave is strong with continuous long period swell.The influence of offshore waves on the hydraulic structures of a coastal power plant cannot be ignored,especially the wave fluctuation in the fore-bay of the pump house.Based on hydraulic model tests,the wave transmission coefficient,Kt,of the water-intake box culvert for Phase Ⅲ of Cilacap CFSPP with different water levels,wave periods and wave heights of incident waves are studied and the factors influencing the wave transmission coefficient,Kt,are analyzed.The test results show that Kt,depends mainly on the wave period,T,of incident waves at the entrance of the box culverts,and the longer the wave period is,the bigger Ktwill be.In addition,the test results of wave transmission coefficient of the water-intake box culvert are applied to the analysis of the wave fluctuations in the fore-bay of the water-intake pump house for Phase Ⅲ of Cilacap CFSPP and a scientific basis is provided for the determination and optimization of the plan layout of the water intake structures for Phase Ⅲ of Cilacap CFSPP.
