Abstract: In order to realize the resource utilization of dredged material generated in sediment cleaning engineering of inland urban rivers,based on the Huangxiao River harnessing project in Wuhan city,we mixed a certain amount of surrounding soil and a certain proportion of JCW curing agent into the dredged material to carry out solidification experiment. We discussed the influence of dosage of JCW cementing agent and organic matter on curing effect and the solidification mechanism. The result showed that the organic matter content had a significant effect on the solidification strength,and the JCW cementing agent had a better effect for the mud compared with cement and lime curing agent. The unconfined strength of solidified mixture reached 520 kPa after 28 days when the organic matter content and JCW curing agent content were 8% and 10%,respectively.
