核电站安全壳预应力束损失与伸长量计算方法

以某核电站工程为例，对其混凝土安全壳预应力束形状进行了描述，分别介绍了环向标准预应力钢束和绕贯穿件预应力束的应力损失及伸长量，并对计算结果进行评价，得出了关于预应力束应力损失和伸长量的规律。

The calculation method of prestressing bundles loss and extension value of nuclear power station reactor containment

With some nuclear power station as example,its concrete reactor containment prestressing bundles shape was described,the stress loss and extension volume of circumferential standard prestressing steel bundles and run through parts were introduced respectively,the calculation result was evaluated,the prestressing bundles loss and extension volume rule was obtained.
