摘要
为研究底渣混合土的力学性能,为工程提供新型填料。将底渣与黏土分别按照1∶0,3∶1,2∶1,1∶1的质量混合成混合土,对四种混合土开展重型击实试验,得到四种混合土的最大干密度分别为：1.650g/cm3,1.752g/cm3,1.753g/cm3,1.721g/cm3,最优含水率为：17.4%,15.4%,16.7%,15.5%。试验结果还表明,随着黏土含量的增加,混合土的击实效果先增后减,在黏土含量为25%-33.3%时获得最优的击实配比。
The paper studied the mechanics performance of municipal soil waste incineration bottom ashes mixed soil in order to provide new packing materials for engineering.It firsr mixed up the MSWI bottom ashes and clay to mixed soil in weight of 1：0,3∶1,2∶1,1∶1,and then tested the heavy compaction for those four kinds of mixed soil.It produced the maximum dry density accordingly as 1.650g/cm3,1.752g/cm3,1.753g/cm3,1.721g/cm3,and the optimum moisture content accordingly as 17.4%,15.4%,16.7%,15.5%.As a result,the tests also indicate that with the increaseof clay content,the compaction effect of mixed soil increases firstly and then decreases.The maximum compaction effect will be produced by clay content as from 25%to 33.3%.
