Abstract：Toanalyzethe physicaland mechanical change laws of reinforcedmarinesoftsoil，this study takes the reinforced marine soft soil in acoastal city as the test sampleandconducts dynamic triaxial testson it.First，the samplesof undisturbed soil，remolded soil prepared by theslurrysedimentation methodand remolded soil prepared by the wet tamping method were sampled and prepared.Then，dynamic triaxial tests and analyses were carried out on theundisturbed soil and remolded soil respectively according to the physicaland mechanical parameter table of the structural members.The test analysis shows that under different loading cycles，there are significant diferences in thedynamic strain amplitude and cumulative plastic strain of the three types of soft soil samples.The dynamic strain laws obtained can provide a scientific basis for the design and construction of marine engineering projects.
