新型核电站常规岛结构设计发展分析

为优化能源结构,拉动内需,国家正大力发展核电的建设,从二代M310到二代半CPR1000,到三代AP1000和EPR,中国核电已进入全面推广"二代半"核电技术同时大力引进"三代"核电技术的时代。本文就"二代"、"二代半"和"三代"核电站常规岛土建技术进行比较,分析常规岛结构设计因核电技术的发展,在汽机基础、结构抗震分析、楼层反应谱、混凝土耐久性设计等方面而相应的技术发展。

Development Analysis of Routine Island Structure Design in New Type of Nuclear Power Station

In order to optimize China energy structure and expand domestic demand,many new nuclear power plants(NPP) are under construction in China and most of them apply CPR1000、AP1000 and EPR technologies. Now there is status in quo that the China-developed 2nd-generation technoloy is popularized and the international 3rd-generation technoloy is being introduced into China.Compared with the 2nd-generation、the China-developed 2nd-generation and the 3rd-generation ,the technologies for the turbine hall structure in conventional island are being developed along with the new nuclear technologies ,including the design of T/G foundation、seismic design 、floor response spectrum and durability design of concrete structures.
