The t-z and p-y nonlinear soil models are implemented for the soils along the piles where the soil springs and dashpots are affected by the pile-to-pile interactions. Both the vertical and lateral pile response are analyzed, and the influences of the loading magnitudes are observed. Following conclusions are drawn: 1.In comparison with the FEM solutions, more compatible results can be founded in the impulsive and steady-state cases, while the difference becomes large for monotonic loads. 2.The equivalent pier model is more suitable in the lateral loading than in the vertical case. 3.The nonlinear single pile response is more significant in the lateral loading than in the vertical cases. 4.The soils at the depth of 0-6m provide the major reactions for the piles deformations. 5.The pile interactions becomes more significant as the pile number increases. In that cases, the deformations of the pile will become smoother. 6.The nonlinear response of the group pile is more significant in the case of monotonic load. 7.The nonlinear group-pile response is more significant in the cases of vertical load.

碩士 === 淡江大學 === 土木工程學系 === 90 === The wave equation analysis is used to model the interactive piles of the pile groups in this study. The t-z and p-y nonlinear soil models are implemented for the soils along the piles where the soil springs and dashpots are affected by the pile-to-pile interactions. Both the vertical and lateral pile response are analyzed, and the influences of the loading magnitudes are observed.
Following conclusions are drawn:
1.In comparison with the FEM solutions, more compatible results
can be founded in the impulsive and steady-state cases, while
the difference becomes large for monotonic loads.
2.The equivalent pier model is more suitable in the lateral
loading than in the vertical case.
3.The nonlinear single pile response is more significant in the
lateral loading than in the vertical cases.
4.The soils at the depth of 0-6m provide the major reactions
for the piles deformations. 5.The pile interactions becomes
more significant as the pile number increases. In that cases,
the deformations of the pile will become smoother.
6.The nonlinear response of the group pile is more significant
in the case of monotonic load.
7.The nonlinear group-pile response is more significant in the
cases of vertical load.
