| Abstract: | Based upon practical experiences in both phases of the Guangzhou Pumped Storage Project,the paper discusses the design assumptions and placement techniques for the concrete block encasing the spiral case of pump|turbine.The discussion covers such issues as the permissible stress level of the spiral case steel,the method of spiral case embedment,the structural reinforcement design of the encasing concrete and the expected vibration absorbing effect of the concrete block. |
