国内外标准中预应力混凝土安全壳结构整体性试验的比较

COMPARISONS OF TECHNICAL STANDARDS AT HOME AND ABOARD FOR STRUCTURAL INTEGRITY TESTS OF PRESTRESSED CONCRETE CONTAINMENTS

结合国内外相关技术标准中对预应力混凝土安全壳打压试验结构强度试验的技术要求,分别对试验周期、升降压过程、验收准则等方面进行对比,指出各标准规定的不同之处。结合某工程安全壳结构强度试验实际情况,给出安全壳压力试验时关于结构强度试验的一些建议,为国内后续同类型机组安全壳结构强度试验的顺利实施提供参考。

Combined with the technical requirement of standards at home and aborad on structural strength tests for prestressed concrete containments, the test cycle, the process and the acceptance criteria were compared, the differences of standards were pointed out. Combined with a structural strength test of raising pressure and descending pressure in a practical project, some suggestions on the strength test in the structural integrity test of containments were proposed, which would provide reference to the successful implementation of the subsequent of structure strength test for containments in China.
