冬季低温条件下核安全相关的混凝土结构设计

CIVIL STRUCTURE DESIGN RELEVANT TO NUCLEAR SECURITY OF NUCLEAR ISLAND UNDER EXTREME LOW TEMPERATURE

以我国北方某核电厂核岛厂房结构为例,采用ANSYS有限元程序建立核岛厂房有限元模型,定量地分析了核岛厂房典型外墙配筋结果,并研究了在冬季低温环境下核岛厂房结构与核安全相关的适应性条件,从而为评估类似气候条件下核岛厂房的防冻安全措施提供参考资料。

The thesis researches on the civil structures of a Nuclear island in Northern China,Applies the ANSYS program to establish finite element model for the nuclear structures,quantitively analyzes the typical external walls reinforcement of nuclear island civil structures,then studies the compatible conditions relevant to nuclear security of nuclear island civil structures under extreme low temperature.,also provides some useful reference materials for evaluating the efficiency of anti-freezing safety measures adopted by nuclear island buildings in similar climate.
