abstract = {In order to improve the strength of Wenzhou silt and conduct resource utilization, solidified agent was used to solidify silt in the laboratory, so as to explore the changes of various physical properties of silt when adding different dosage of solidified agent. Besides, the solidification test of the silt was carried out in the field, the cone penetration test and load plate test were used to evaluate the bearing capacity of the solidified silt, exploring the solidification effect of the solidified agent on the silt in the actual engineering. The laboratory test results show that when the dosage of solidified agent is more than 4%, the compression coefficient of the silt decreases obviously, and the engineering properties of the soil are effectively improved. When the dosage of solidified agent is 8%, after curing for 28 days, the cohesion and internal friction angle of solidified sludge are 216.25 kPa and 28.6°, respectively. The cone penetration tests show that when the dosage of solidified agent is 4 ~ 8%, the characteristic value of bearing capacity of solidified silt is 121.52 kPa ~ 146 kPa. The bearing capacity of soil under plate load test is higher than that of cone penetration test. The dosage of 4% ~ 8% solidified agent can be used as an effective reference in the actual project of resource utilization of Wenzhou silt.}
