回顾和总结了秦山核电厂的预应力混凝土安全壳设计全过程,简单地介绍了对预应力钢丝束的试验,描述了结构型式、设计基准和分析方法,并扼要地指出了混凝土防裂考虑和后张体系及钢衬里设计的概貌,介绍了对秦山核电厂安全壳结构极限承载性能所进行的模型试验及非线性分析研究。最后介绍了秦山核电厂安全壳的整体性试验,指出秦山核电厂的安全壳试验实测值与预期值相符,结构性能良好,气密性也完全符合要求。 The whole process of prestressed concrete containment design in Qinshan NPP is reviewed and summarized. The test of prestressed steel wire bundle is briefly introduced. The structure type, design basis and analysis method are described. The anti-cracking considerations and The post-tension system and the design of steel lining, the model tests and nonlinear analysis on the ultimate bearing capacity of containment structure of Qinshan NPP are introduced. At last, the whole experiment of containment of Qinshan NPP is introduced. It is pointed out that the measured value of containment in Qinshan NPP is consistent with the expected value, and the structural performance is good and the airtightness fully meets the requirements.
