Abstract: When construction embankment upon soft ground, settlement and stability are most important problems to be considered. Based on Xiaonianwei construction on Nanjing Yangtze Dike upgrading project, field monitoring and tests on embankment construction process upon soft ground are carried out. The monitoring projects contain surface settlements, layered settlements, lateral displacements of soil, soil pressure, pore water pressure and the groundwater table, etc. Based on Plaxis software, numerical simulation model on embankment construction process upon soft ground is built. The accuracy and reliability of numerical simulation model is verified by comparative analysis with field monitoring results. Then, the settlement influenced by key indicators of construction control factors, such as filling rate and filling intermittent time, is discussed and analyzed. The results show that the whole settlement increases with single filling thickness increasing; while the influence becomes little when single filling thickness less than 1 m. Hence, the single filling thickness with 0.5－1.0 m is suggested. The research results can provide a reference to construction quality control upon soft ground in similar places.

Key words: soft ground, embankment, filling speed, field test, numerical simulation
