摘　　要：吹填土由水力吹填形成,颗粒很细,固结性能差,吹填以后要经过很长时间才能自然沉积固结,待表面形成硬壳后方可进行加固处理.为缩短沉积固结时间,在室内采用多种固化材料对吹填土进行固化处理试验.通过对多种添加方式的固化土样无侧限抗压强度试验的结果进行对比分析,优选出了适宜的固化方案.The dredger fill is formed under hydraulic dredging, with characteristics of fine particle and weak in consolidation capability with slow natural sedimentation and consolidation process, and it takes a long time to achieve the consolidation completely. Only when the surface duricrust has formed, should the ground improvement treatment be started. To accelerate the consolidation, we made consolidation tests of dredge fill with kinds of additive are made in laboratory. Comparing the results of the tests of vertical pressure without side limit of soil samples, an appropriate solidified project is found.
