Analysis on powerhouse vibrations with spiral cases in different embedding manners for large-scale hydropower station

OUYANG Jinhui1,2,CHEN Houqun1,2,ZHANG Chaoran3(1.China Institute of Water Resources and Hydropower Research,Beijing 100048; 2.State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin,Beijing 100038; 3.China Three Gorges Corporation,Beijing 100038)  
How to select the embedded manner of turbine spiral case is important but difficult to the design and development of powerhouse of the large-scale hydropower stations in west China.In combination with the Three Gorges powerhouse design,the paper adopts a nonlinear model of double-nodes contact element to simulate the vibration responses of powerhouse with spiral case embedded in different manners,focusing on three structures,i.e.interface among concrete,cushion layer and spiral case.The results are summarized as follow.1) In terms of concrete structure vibrations,the minimum responses occurs in the spiral case embedded in concrete holding a certain water head inside(MHWH),while the maximum responses in the manner of direct embedding in concrete(MD).The responses in the spiral case embedded in concrete with cushion layer(MCL) are obviously greater than that of MHWH.2) In terms of vibrations in spiral case and other metal components,the responses of MHWH,MCL and MD are in a decreasing order and MD is the most favorable to the metal components.To verify the model and the results,an in-situ test of powerhouse vibrations was conducted for the Three Gorges station under the water level of 145m,and it shows results quite similar to the model predictions.The only difference is that the responses of MCL in the test is close to that of MHWH.An explanation for this is that in the test case of MCL,there existed gaps between the spiral case and the concrete or cushion layer,which damped the transmission of vibration from spiral to its surrounding concrete.
