By taking the importance of seepage parameters into account during the suction process, a comparison analysis of seepage field between bucket foundations with (C-BF) and without multiple subdivisions inside (N-BF) is performed in this paper, with the consideration of tilt adjustment as well as the complexity in underwater soil. Scaled model experiments were conducted at first to acquire the excess pore water pressure μ e , and then the law of three-dimensional heat conduction was used to simulate the seepage field and the parameters of the two models. The results of simulations were compared with those of the model experiment, and it is shown that the computational results agree well with those of experiments; N-BF is more sensitive to the tilting of the bucket body than C-BF; the layered soil can protect the seepage filled with limited hydraulic gradient and seepage flux; basically the seepage field variations with the same internal structure under different working conditions have their own regularities.
