Research on Natural Settlement Rule of Dredged Silt in Tianjin Binhai Region

Abstract:

Main research object of this article is marine dredging silt in Tianjin Binhai region. It discusses natural settlement rule of dredged silt with different moisture content in Tianjin Binhai region through conducting indoor natural settlement model experiment to dredged silt of different moisture content. The results indicated that natural settlement of dredged silt in Tianjin Binhai region can be divided into three stages: the first stage is quick subsidence stage within 4-5 hours at the start of the experiment, during which settlement rate of dredged silt is fast and settlement volume is large; the second stage is natural deposition transition section stage within 2 days after the experiment, when settlement rate of dredged silt starts slow down but settlement volume is obvious; the third stage is dead-weight consolidation settlement stage of slow settlement after 2 days since the start of the experiment, in which settlement rate of dredged silt is slow and settlement volume is less. Settlement of Dredged silt in Tianjin Binhai region is greatly influenced by its initial moisture content. The higher the initial moisture content is the faster initial settlement rate of dredged silt will be and so is the final settlement volume of dredged silt.
