The article is based on the deep hydraulic fill soft soil foundation treatment project in Xuwei Port Area,Lianyungang,Jiangsu.It constructs a 3D finite element model of a new type of concrete large slab port area surface layer and solidified soil yard foundation.By varying the uniformly distributed load,panel size,and solidification layer design parameters,the study investigates the changes in soil and panel responses caused by these variations.The findings reveal a direct proportional relationship between the maximum surface settlement and the uniformly distributed load.Under uniformly distributed load conditions,an increase in panel thickness and side length leads to a greater maximum settlement,whereas an increase in solidified layer thickness and modulus results in a corresponding decrease in surface settlement.However,compared to the side length,the effect of panel thickness is less significant.Additionally,as the key influencing factor,the solidification layer parameters gradually diminish their impact on controlling surface subsidence as their values increase.
