摘　　要：高能同步辐射光源项目储存环隧道重晶石混凝土墙是辐射防护的关键,是保证进行实验的科学家身体健康及周边环境安全的防护盾。重晶石混凝土浇筑量终极收缩值控制均为国内首例。此项技术的研究实施创造了国内环形辐射防护混凝土的先例,积累了丰富的数据,突破了多个技术难关,取得了多项专利技术。此项研究推动了辐射防护混凝土施工技术的发展,为后续同类大科学装置施工奠定了基础。Storage ring tunnel barite concrete wall of high energy photon source project is the key point of radiation protection and it is also a shield protecting scientist’s physical health and surrounding environment safety. Control of barite concrete grouting final shrinkage value is the first case in China,and this technique is also the first circular radiation protection concrete project in China, accumulating abundant data, successfully solving many technical difficulties and obtaining several patent technologies.This research promoted the development of radiation protection concrete construction technique, providing a solid basis for future similar large scientific facility construction project.
