AP1000核电厂OLP型预埋件有限元分析方法研究

OLP embedment design method research for AP1000 nuclear plant

作为世界上最先进的第三代核电技术,AP1000首堆正在中国建造。AP1000核电站厂房的一大特点是模块化程度高,以钢板混凝土模块墙结构取代传统的钢筋混凝土结构,模块墙上需要布置大量的OLP(Overlay Plate)型预埋件以连接其它结构构件,比如支撑工艺管道、设备支架、操作平台、预制构件等,因此预埋件的设计是AP1000结构设计中十分重要的环节。本文介绍了预埋件的有限元分析方法,将开发的GTStrudl命令流模板和基于Microsoft Excel环境下的VBA宏处理程序应用于预埋件的设计,显著提高了工作效率,对工程设计具有一定的帮助和借鉴意义。

Background： One of the most advanced nuclear power technology, the first AP1000 reactor is under construction in China. Modularization is one of the main characteristics for AP 1000 nuclear plant building. Module wall with steel face plate is used instead of reinforced concrete structure wall. A number of OLP embedments need to be installed into the module wall to connect other structures such as pipes, equipments, operation platforms and any other component attached to the module wall. Therefore, the design of embedment is very important in AP1000 structural design. Purpose： A finite element analysis method and tool for embedment design is needed for convenience. Methods： This paper applies the self-developed GTStrudl command template and VBA macro program for embedment capacity calculation and evaluation based on Microsoft Excel to the embedment design. Results： A Microsoft Excel template for embedment design is developed. Conclusions： The analysis method and template brings reasonable results and may provide some help and use for reference for the engineering practice.
