核电站大模板体系防连续倒塌设计与施工

Anti-nuclear Power Plant large Formwork System Design and Construction of Progressive Collapse

一方面,以防连续倒塌控制和"结构延性"的设计概念为目标,结合模板设计规范的要求,对核岛大模板结构提出了多方面的设计控制要求,比如大模板结构体系应选择多次超静定结构、大模板高强拉杆采用设计强度值和大模板关键构件失效后的防连续倒塌控制;另一方面,从大模板施工管理的角度,对不同的影响因素进行了原因分析,并提出了有针对性的防治对策。

On the one hand, to control and prevent progressive collapse ＂ductility＂ design concept as the goal, combined with the requirements of the template design specifications for the nuclear island large template structure proposed various design control requirements, such as large template architecture should be selected many times statically indeterminate slructure, high strength rod formwork design with anti-strength values and the large template key member of the progressive collapse after the failure to control, on the other hand, large formwork construction management from the perspective of different influencing factors cause analysis, and proposed targeted countenneasures.
