恰希玛核电站安全壳预应力应用了１９Ｔ１６ 后张群锚体系，单束张拉力约３８００ｋＮ，分５ 级张拉预应力筋，采用应力控制、伸长值校核的双控措施，严格遵循对称施工的原则
The 19T16 post-tensioned group anchor system was used for the prestressing of the Chashma nuclear power plant containment. The single beam tensile force was about 3800 kN. The prestressed tendons were divided into 5 stages and the double control measures of stress control and elongation were used to strictly follow the symmetry. The principle of construction
