The safety level of the wharf revetment construction in eastern Yantian Port is high and the design load is large.In view of the problems of deep burial,large thickness and wide distribution of the poor geological soft soil layer beneath the revetment,the soft foundation treatment scheme is studied,so as to determine the appropriate soft foundation treatment method and improve the overall stability and safety factor of the revetment.Four soft foundation treatment schemes are proposed,including excavation and replacement scheme,cement mixing pile scheme,gravel pile scheme,and lightweight soil scheme.The calculation results show that the overall stability and safety factor of the revetment can meet the requirements after adopting the four soft foundation treatment schemes.After comprehensive comparison from the aspects of cost,construction convenience,reliability and construction period,and referring to the construction requirements,the excavation and replacement scheme is adopted for weak soil treatment.The advantages of the recommended scheme are superior safety,convenient construction,mature technology,and easy quality control.
