摘　　要：核工业的生产会产生大量的核废物,如何安全处置这些核废物尤其是高放废物(HLW)日益成为摆在人类面前的严峻问题。本文通过轻型、重型压实实验得出击实功是影响压实性能的一个重要因素;添加一定量沸石或凹凸棒石可以得到较大的最大干密度和较小的最优含水率。在沸石或凹凸棒石添加为0～20%时混合材料的干密度增加不大,压实曲线相对平缓;随着沸石或凹凸棒石增加到20%～50%时,压实干密度急剧增大,但考虑到增加沸石或凹凸棒石超过50%时所需的压实功较大,因此沸石或凹凸棒石的含量在20%～30%较容易压实。Nuclear industry production will produce large amounts of nuclear waste,how to safely dispose of the nuclear waste especially high level radioactive waste（HLW） becomes increasingly serious problem at present.This article turned out that compaction work was an important factor of the impact compaction performance through the light and heavy compaction experiments;adding a certain amount zeolite or attapulgite can get larger maximum dry density and smaller optimal moisture content.In zeolite or attapulgite add to 0～20% of dry density increases mixed materials,compaction curve was relatively tame;with zeolite or attapulgite increased to 20% to 50%,the pressure increased sharply,but when zeolite or attapulgite increasing more than 50%,the pressure of the compaction needed higher,so the content of zeolite or attapulgite in 20% to 30% was easier to compact.
