Abstract Some geo-environmental problems under pile foundation constructionarestudied. The physical and mechanical parameters of soft clay under construction disturbance are analyzed. The method for calculating squeezing stress and excess pore pressure by elastic-plastic theory is deduced. The variations ofstress stateand structure of soil are discussed. The deformation and stability of soft clay mass arealso analyzed. Besides, the bearing capacity of pile under pile driving and its changes withtime after constructionare also discussed.
