Experimental Study of Vacuum Combined Tidal Energy Pre-pressure Technology for Soft Ground Treatment
A soft soil treatment technology combining tidal energy and vacuum pre-pressure is proposed to achieve green municipalities,energy saving and emission reduction,and assist the national"carbon peaking and carbon neutral"strategy.This technique makes full use of the tidal water level difference for the pre-pressure field with low frequency cy-clic loading,meanwhile the vacuum pre-pressure enables the soft soil to be drained and consolidated with cyclic compres-sive stress at the same time.The soil becomes more compact by the pore water pressure between soil particles under cy-clic loading dissipates at a rapid rate,prompting horizontal creep in the soil between the drainage boards and improving the bearing capacity and stability of the foundation.Through model tests,it is found that this technology can improve the bearing capacity of the foundation,eliminate most of the foundation rebound deformation,shorten the construction period and save investment.Combining the tidal characteristics,it is proposed to apply the tidal energy to the treatment of soft soil in coastal areas by using the principle of linker,and the transformation scheme of research results is proposed.
