伴随着宽级配砾质土作为心墙防渗料在土石坝工程中的广泛应用，对其工程特性的研究已成为水利工程研究的热点问题。通过室内试验，研究了添加减水剂对宽级配砾质土击实性能改良的影响。通过轻型和重型两种击实方案，对比研究了未添加减水剂与添加减水剂下两种宽级配砾质土试样的压实特性，研究表明：添加减水剂的土样可以在较小的击实功下得到较大的干密度，并在一定程度上降低最优含水率。

Along with the wide application of wide-grading gravelly soil as the material of earth-rockfill dam’s core wall, the research on its engineering properties has been a hot issue of water conservancy engineering.Based on indoor com-paction tests,the effect of water-reducing agent on the compaction performance of wide-grading gravelly soil is studied. Through light compaction tests and heavy compaction tests,the compaction characteristics of two wide grading gravelly soils,adding water-reducing agent or not,are compared and studied.The study results show that the maximum dry den-sity of the wide-grading gravelly soil is increased,and its optimum water content is reduced by adding the water-reducing agent.
