摘要
列举了巴贡水电站溢洪道闸墩预应力锚索施工中经常碰到的一些问题,如锚索伸长值计算、测力计与千斤顶读数偏差判定、孔道灌浆体强度测定及预埋件安装等,进行分析,给出了解决的办法。
The common questions in the prestressed cables construction in the spillway piers of Bakun Hydropower Station are enumerated.Such as the calculation of the cable elongation,the judgement of the reading tolerance between the load cell and the jeck,the measurement of duct grout cube strength,and the fixing up of embedded parts in place etc.The solutions related to them are described.
