Abstract

The invention discloses a simulation test method for vacuum preloading treatment construction period prediction, which comprises: dredging the seabed sediments into a cofferdam at the tidal flat for reclamation; after the dredging operation is completed, the construction site is stopped until it is completely deposited; and slurry soil samples are taken Carry out laboratory tests; first conduct indoor tests to test parameters, then simulate with the finite element model, and finally write the actual engineering results in the actual case to match the simulated results. The final stable values ​​of foundation settlement and pore water pressure dissipation with larger plastic drainage board spacing are smaller than those with smaller spacing.

Description

technical field [0001] The invention relates to the field of vacuum treatment of dredged fill soil, in particular to a method for predicting construction period design and construction period of vacuum treatment. Background technique [0002] With the rapid development of coastal cities, the demand for land continues to increase. Land reclamation by dredging silt is an effective way to solve the shortage of land resources. "Artificial" ground has to be modified to be used as a building site because mud is a mixture of fine particles and a lot of water, so it has very low strength. Vacuum preloading is a soft ground treatment method commonly used in industry. It installs prefabricated vertical drains in the soil and connects them with vacuum pumps. However, it is not uncommon to report that improvements in vacuum treatment of dredged silt have not been effective. It has been reported that settlement, pore water pressure dissipation and water production are significantly de...
