大型核电主厂房节点优化设计工艺探讨

Discussion on the node optimization design process of large nuclear power plants

大型核电主厂房跨度大、节点多、结构比较复杂,目前对主厂房的节点设计大多只考虑节点的受力情况,而忽略了主厂房各构件的制作、运输和安装的难易程度,通过对大跨度主厂房节点的优化设计方案探讨,使主厂房构件在保证原节点受力要求的前提下,降低了构件的施工难度、节约了运输和安装的成本。

At present,due to the large span,multiple nodes,and complex structure of the large nuclear power plant,most of the node designs of the main plant only consider the force of the node,while ignoring the difficulty of making,transporting and installing the components of the main plant.This paper discusses the optimal design scheme of the large-span main plant nodes,so that the main plant components can reduce the construction difficulty of the components and save the transportation and installation costs while ensuring the force requirements of the original nodes.
