For the purpose of foundation and structure stability during the construction of tide embankment,three monitoring projects including embankment settlement monitoring,berm platform settlement monitoring and pore water pressure monitoring are installed.The result shows that foundation appears oversize instantaneous settlement on account of high construction speed,short loading interval at initial stage.Following with the shaping of embankment,stable monitoring data range,slow change rate and high dissipation speed of pore water pressure arise.Based on actual embankment settlement data,consolidation degree of soil mass is high and foundation stability becomes strong by calculating of hyperbolic curve.
