Abstract: | In calculation of reinforcement for the peripheral concrete of the volute structure of a pumped storage power station, the three dimensional finite element calculation software is adopted to select the pre-pressure for volute structure. Based on the specifications, the according reinforcement schemes for the peripheral concrete in various conditions are obtained. By comparative analysis of various factors, a relatively rational pre-pressure for volute structure is selected. Meanwhile, some experience and rules are summarized in the process of selection analysis which is worthy of reference. |
