| Abstract: | in this paper, the feasibility on engineering application of up-date penstock has been researched by the monolithic model test on spatial open penstock behind dams. Such penstock both cancelling the parts of triple expansion joint and anchorage block and adopting-self-support structure has apparently advantages over the traditional penstock. Some results or equivalent stresses in measuring points of the model under coupling action of variant operation modes have been given and compared with the results calculated by SAP-V programm. |
