摘要
Due to the different material composition and depositional environments,the engineering properties of soft dredger soil varied widely and also has regional characteristics.In order to probe the mud-water interface,water content and void ratio changes in the procession of subsidence and post-depositional characteristics of Tianjin soft dredger soil,the large-scale settlement column is designed to simulate the natural sediment of the mud,and its micro-structure is also studied.The test results show that Tianjin soft dredger soil is rich in clay minerals,and its micro-structure is unstable.In the procession of deposition,the particle sorted apparently.Its indicators varied greatly in the early,but later stabilized.
