摘要
无粘结预应力锚索在水电工程边坡支护中经常遇到,文中对溧阳电站边坡无粘结预应力锚索设计参数、张拉施工方法、实际伸长值量测和理论伸长值计算方法、张拉的质量控制等进行了详细的总结和说明,最后通过与安装的锚索测力计测值进行对比,说明张拉质量完好,满足设计要求。
Prestressed anchorage cables without bond are often encountered in slope support of hydropower project.This paper has made a detailed summary and explanation of the design parameters of prestressed anchorage cable without bond,the tension construction methods,the measurement of actual elongation value and the calculation method of theoretical extension value,the tensioning quality control in the Liyang Power Station.Finally it proves the tensioning quality is good and the design requirements are satisfied by contrasting with the measured values of its anchorage cable dynamometer.
