Evaluation of Undrained Shear Strength of Converting Dredged Material to Agricultural Soil
In order to keep the river and harbor clear, the dredging activity need to be done continuously which has generated millions of cubic meters of dredged material (DM) every year in China. It is an economical and environment-friendly alternative of DM disposal to convert the dredged material to agricultural soil (CDMTAS) by adding admixture and/or dewatering. However, the corresponding evaluation criteria has not been reported so far to determine whether these treated DM are available for using as agricultural soils or not. 145 groups of data composed of weight and the shoes size of the adult was obtained by surveying in China, and a safety factor was given during the statistical analysis of the foot plantar pressure on the ground of adults, and 50 kPa is recommended for human agriculture activity loading on CDMTAS whose process could be regarded as undrained shear. Moreover, 16 kPa is recommended for the least undrained shear strength of CDMTAS that is required for bearing the human agriculture activity.
