摘　　要：通过对放射性固体废物桶内压缩过程的研究，建立了废物桶内一维应力压缩模型，并根据模型设计最优压缩策略对放射性固体废物装填进行指导。结果表明，不同的压缩策略废物的装填总量以及压缩后的桶内装填效率差别较大，装填总量相差1倍左右，装填效率相差20％～30％。采用压缩策略的装填方式较无序装填方式在废物减容方面提高10％左右，且废物装填次数也显著降低，符合工程应用与废物最小化要求。The one‐dimension stress compression model was built through the research on compression in drum for radioactive solid waste . The compression process was optimized by taking advantage of that model , and filling process of radioactive solid waste was guided .The test results show that big differences exist in total volume of filling and efficiency of filling after pre‐compression for different models .Comparing the best model with the worst model ,the volume of filling can double and the efficiency of filling increases 20%‐30% . T he volume reduction ratio increases 10% and times of waste filling obviously decreases guided by compression strategy compared with random filling .It can well meet the requirements of waste minimization and future operation .
