Study on the characteristics of bank slope and pile-supported wharf under yard loads
Long-term loading of the yard can lead to significant deformation of the soft soil,affecting the stability of the bank slopes and threatening the safety of the adjacent wharf structures during the operation and maintenance period.Based on the engineering prototype of a typical pile-supported wharf in Tianjin port,the three-dimensional finite element analysis model considering soft soil,pile-supported wharf and loading was developed.The structural response characteristics of soft soil and pile-supported wharf under yard loads were investigated.The results show that yard loads can lead to significant settlement of the ground surface,as well as lateral movement of soft soils underneath the shore connecting structure.The piles on the rear platform undergo significant horizontal deformation and generate significant bending moment response at the top,which can lead to concrete cracking damage at the pile cap.The reduction in width of yard loads has a small effect on the peak displacements of the soil and structure,but significantly affects the settlement range of the soil.Relative slip between the pile cap and the superstructure occursin the absence of heaped loads on the rear platform,which can cause misalignment and breakage between the members.
