By field-testing methods, such as static cone penetration test, field vane shear test, and pore water piezometer test, the variation of strength and the pore water pressure are measured at real time, and the marine hydrodynamics' impaction on the consolidation process of the sediments in the Yellow River Estuary was studied. It is shown that the self-consolidated sediments have a very fast consolidation rate, under self-consolidation, in 72h, the consolidation degree reaches 37% and about 142h the pore water pressure disperse over, while under the hydrodynamics, in 72h the consolidation degree reaches 52% and about 195h the pore water pressure disperse over.

Firstly, the soil samples are gathered from the same section such as surface layer soil samples gathered from 0cm to 15cm depth and representation on studied object. Secondly, the precondition of tested samples must be the same. This study indicates that the tested samples must be 1mm diameter, over-dried at 40℃ for 24h and airtight cooling for 24h before measured for air-dry samples, and softly planish the surface at measuring. Lastly, the illuminating condition of light must be the same. This study indicates that the testing geometric condition are light source angle 15°, light source distance 30cm and sensor distance 15cm for soil hyperspectra indoor. The surface of white reference must be the same plane of that of sample.
