【Abstract】 The third-phase Dongjiang-Shenzhen water supply extension project is very important in providing industrial and municipal water for Hongkong and Shenzhen. Based on the model test of the first cascade pumping station──Dongjing pumping station, this paper makes a systematic analysis of the hydrologic silt behaviour, river bed evolution, the intake location selection, intake layout pattern and siltation-proofing measurement. the experimental results agree with the practical engineering facts and a great economic benefit is gained.更多还原
