摘要
本文通过坝后空间明弯压力钢管的整体模型试验研究,验证了采用自承方式(不设置三向伸缩节和镇墩)的压力钢管工程应用的可行性,给出了在诸多工况因素偶和作用下,试验模型测点处的应力及相当应力。其成果与SAP—V电算结果进行了比较。
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.
