Advance in research and application of spiral case structure with a membrane in hydroelectric power plant
摘要
Abstract
The development in the research and application of spiral case structure with a membrane（SC- SM） in hydroelectric power plant, is summarized. It is indicated that SCSM is the trend in development of selecting the embedding type for spiral case. Two significant advances are pointed out： the joint stressing of spiral case and surrounding concrete, the sliding friction between them. The nonlinear mechanical behav- ior of membrane material as a factor influencing significantly the SCSM research should be considered in the future. The influences of membrane＇s material and space property on the structural performances of SC- SM are respectively stated, and on that basis the existing problems of the SCSM research are concluded. Fi- nally, it is suggested that the of concepte control should be the focus of research in SCSM and the mem- brane could be regarded as a controlling measure. To explore the theory and measure for controlling the structural performances of spiral case structure from the viewpoint of effect of membrance should be the im- portant topics of research in this field.关键词
