摘　　要：为研究高含水率疏浚软土经过流动固化处理后的工程力学特性,制备了一系列试样,开展无侧限抗压强度试验,分析了养护龄期、固化材料掺量、浸水时间对疏浚软土力学性状的影响。结果表明,固化材料掺量和养护龄期的变化对试样的无侧限抗压强度有较为显著的影响,而浸水时间对试样无侧限抗压强度影响较小。随着固化材料掺量和养护龄期的增加,土体强度增强,试样破坏应变降低,割线模量提高,试样趋向发生脆性剪切破坏。The curing treatment of dredged soft soil is of great significance to the development of ecological balance.In order to study the engineering mechanical properties of dredged soft soil with high water content after flow curing treatment,a series of specimens were prepared to carry out the unconfined compressive strength test,and the effects of curing age,curing material dosage,and soaking time on the mechanical properties of dredged soft soil were analyzed.The results show that the changes of curing material dosing and maintenance age have a more significant effect on the change of the unconfined compressive strength of the specimens,while the soaking time has a smaller effect on the unconfined compressive strength of the specimens.With the increase of curing material doping and maintenance age,the strength of the soil body is enhanced,the destructive strain of the specimen is reduced,the cut line modulus is increased,and the specimen tends to undergo brittle shear damage.
