Experimental study on optimization of energy dissipators in spillways of Xiaoshixia Hydropower Station

LI Lin1,2,GE Xu-feng1,2,TAN Yi-hai1,2,XU Shi3,QIU Xiu-yun1,2(1.College of Water Conservancy and Civil Engineering,Xinjiang Agricultural University,Urumqi 830052,China;2.Agricultural and Water Saving Research Centre,Xinjiang Agricultural University,Urumqi 830052,China;3.Reconnaissance and Design and Research Institute of Water Conservancy and Hydropower of Xinjiang Uygur Autonomous Region,Urumqi 830000,China)  
The structural shape of the energy dissipator in the original design scheme was optimized based on the hydraulic model tests on the spillway of Xiaoshixia Hydropower Station on Kumalake River,Xinjiang.The model tests indicated that for the original design scheme,under the design flood discharge of 1 856.20 m3/s with the return period of 30 years,complete hydraulic jumps could not be formed in the plunge pool,violent fluctuations occurred before and the hydraulic jumps,and water mostly overflowed.The height of side walls and the length of the plunge pool could not satisfy the flow discharge requirements.Through many groups of model tests,the depth of the plunge pool was reduced,and conventional plunge pool in the original design scheme was replaced by the synthetic plunge pool with baffle piers,baffle blocks and low dissipation sills.Model tests on the spillway were carried out under the design discharge of 1 856.20 m3/s.The test results show that under the combined action of baffle piers,baffle blocks and low dissipation sills,forced hydraulic jumps have formed,and the flow pattern is obviously improved.Meanwhile,the length of the hydraulic jumps decreases and their second conjugate depth also decreases.The rate of energy dissipation has increased.To this end,under the premise of ensuring the rate of energy dissipation,the synthetic plunge pool with baffle piers,baffle blocks and low dissipation sills can effectively reduce the length of the plunge pool and the height of its side walls and to save the construction cost.The test results can be referred by the design of optimization projects and the optimization of plunge pools for other similar projects.
