巴拉水电站溢洪洞进口闸室预应力闸墩锚索布置设计OA
Design of pre-stressed pier anchor cable layout for the intake gate chamber of the spillway tunnel at Bala Hydropower Project
为研究巴拉水电站溢洪洞进口闸室预应力闸墩在施工和运行过程中的应力应变情况,采用三维有限元软件进行整体建模,通过对比闸墩锚索布置、张拉吨位等参数,计算各工况下闸墩应力应变有效改善情况,以最终确定溢洪洞闸室预应力锚索布置形式,其研究成果可为类似工程提供参考.
To investigate the stress and strain behavior of the pre-stressed pier for the spillway tunnel intake gate chamber at Bala Hydropower Project during its construction and operation phases,a comprehensive three-dimensional finite element model was developed.By comparing parameters such as the layout of anchor cables and the tensioning tonnage,the study calculated the effective improvement in pier stress and strain under vari-ous working conditions.The optimal layout of the pre-stressed anchor cables for the spillway tunnel gate chamber was ultimately determined.It is expected that the findings from this research will provide a valuable reference for similar engineering projects.
