摘　　要：质子医疗作为当今肿瘤治疗的先进技术,对防辐射设施提出了极高要求。由于质子能量极高,需采用超厚钢板墙作为生物屏蔽体。传统施工工艺无法满足超大尺寸、超厚实体钢板墙的制作和安装需求。针对此问题,创新性地提出了“错位拼装-节点锚固-框架支撑”的新型钢板墙施工工艺。将钢板墙横向错位分段拼装,有效避免超限构件;采用新型耳板锚栓连接,确保钢板墙与扶壁柱牢固可靠;引入门式框架支撑体系,保证安装精度和结构稳定性。该工艺通过建模仿真优化施工方案,最大限度地降低变形和应力集中风险。实际工程应用表明,新工艺显著提高了施工效率和结构可靠性,减少返工和质量通病,达到了预期的经济效益和社会效益。该成果为特殊工程中超大型异形厚实钢结构的施工提供了新思路。As an advanced technology of tumor treatment,proton medicine has put forward high requirements for radiation prevention facilities.Due to the high proton energy,the ultra-thick steel plate wall should be used as a biological shield.Traditional construction technology cannot meet the production and installation requirements of super-large,ultra-thick solid steel plate wall.In view of this problem,this paper innovatively puts forward the new steel plate wall construction technology of"dislocation assembly-node anchorage-frame support".Organize steel plate wall in transverse dislocation to effectively avoid over-limit components,adopt new ear plate anchor connection to ensure firm and reliable steel plate wall and support post,introduce portal frame support system to ensure installation accuracy and structural stability.The process optimizes the construction scheme through modeling and simulation to minimize the risk of deformation and stress concentration.The practical engineering application shows that the new process significantly improves the construction efficiency and structural reliability,reduces the rework and common quality problems,and achieves the expected economic and social benefits.This result provides a new idea for the construction of super large special-shaped thick steel structure in special engineering.
