摘　　要：文章针对采取浅地表处置且地下水埋深较浅的低、中水平放射性固体废物处置场场址,结合北方某处置场的设计实践,对其场址自然条件进行分析,针对自然条件的不足,提出一种降低地下水水位的截水盲沟设计设想,并对该设计的长期有效性和长期稳定性进行论证,以实现处置场在运行时,其与地下水的安全隔离。文章结合工程实际,对提高处置场本质安全度进行研究,提出处置场设计的新思路,为后续处置场的设计提供帮助和参考。Aiming at the disposal sites for low-and intermediate-level radioactive waste which adopt shallow surface disposal and has shallow groundwater depth,combined with the design practice of a disposal site in the north of China,this article analyzes the natural conditions of the site,proposes a design of the intercepting blind ditch to reduce the groundwater level according to the shortcomings of natural conditions,and demonstrates the long-term effectiveness and long-term stability of the design,so as to realize the safe isolation of the disposal site from groundwater in operation and supervision.Combined with the actual project,this paper studies the improvement of the intrinsic safety of the disposal site,and puts forward a new idea to design the disposal site,so as to provide help and reference for the further design of disposal sites.
