摘要: 为开发500 t靶物质级的探测器物理模型,通过借鉴其他成功建造的中微子探测器结构形式,提出了锦屏中微子探测器的结构方案。与常规结构设计不同,为了满足超深地下环境以及物理实验要求,锦屏中微子探测器的钢结构在材料选择、多功能承载以及施工空间限制等方面面临挑战。因此,重点针对锦屏中微子探测器不锈钢结构设计方案进行了分析,包括不锈钢框架、不锈钢板以及不锈钢球形网壳。结果表明,不锈钢框架、不锈钢板和不锈钢球形网壳均满足强度和刚度的设计要求,从而验证了锦屏中微子探测器不锈钢结构设计方案的安全性和可靠性。Abstract: In order to develop a 500-tonne target material-level detector physical model, the structural scheme for the Jinping neutrino detector has been proposed by drawing on the structural designs of other successfully constructed neutrino detectors. Unlike conventional structural design, the steel structure of the Jinping neutrino detector faces challenges in material selection, multifunctional load-bearing, and construction space constraints to meet the requirements of the ultra-deep underground environment and physical experiments. This paper focused on the analysis of the stainless steel structural design scheme for the Jinping neutrino detector, including the stainless steel frame, stainless steel plates, and stainless steel spherical grid shell. The results demonstrated that the stainless steel frame, plates, and spherical grid shell all met the design requirements for strength and stiffness, confirming the safety and reliability of the stainless steel structural design for the Jinping neutrino detector.
