核电厂安全壳结构整体性试验,是核电厂交付使用前对安全壳结构进行的一次全面检测,以评判安全壳的实际性能是否满足设计要求。通过安全壳混凝土试验过程中应变分析,平均应变为线性,且平均应变和位移具有可逆性,恢复性好,与理论计算比较,二者吻合性较好,偏差较小,满足整体性试验验收标准。 The integrity test of containment structure of nuclear power plant is a comprehensive inspection of containment structure prior to the delivery of nuclear power plant to judge whether the actual performance of containment meets the design requirements. Through the analysis of the strain during the test of concrete containing concretes, the average strain is linear, and the average strain and displacement are reversible, and the recovery is good. Compared with the theoretical calculation, the agreement between the two is good and the deviation is small, which meets the requirement of integral test and acceptance .
