Experiment Study of Dredger Fill Using Different Consolidation Methods

Abstract:

At present, there are many methods of the dredger fill foundation treatment, in which the most widely used application of vacuum preloading method. The dredger fill for test was taken from the Tianjin Binhai new area center fishing port area, separately carried on the self-weight consolidation and vacuum preloading consolidation. Through the indoor test of soil test physical and chemical parameters, comparing the moisture content, soluble salt amount and component, caption exchange capacity, PH value and physical and chemical index. The results show that: the clay content of soil sample in the central fishing port area is higher, degree of aggregation is high, liquid limit is less than 60%, Ip is more than 10, belongs to the low liquid limit clay. Relative self-weight consolidation, soluble salt content of soil samples after vacuum preloading drainage treatment are low, but the particle size composition change less. It is said that parts of salt in the soil samples discharge with water discharge in vacuum preloading process, vacuum preloading effect is better.
