Computer modeling for pile-soil response under the horizontal head load

Piles are widely used in foundation engineering. Much work has been done in the area of dragload on piles subjected to surcharge or consolidation of surrounding soils; much less work has been done on pile behavior under the horizontal pile head load. The writers believe that the effects of horizontal pile head load on dragload changes remain ambiguous among engineers. To obtain detailed information on the behavior, it is necessary to simulate the 3D geometry and nonlinear behavior of the soil. So in the present paper, the behavior of pile subjected to horizontal pile head load is analyzed by the three-dimensional (3D) interaction between the soil and the piles, whose result reveals the mechanism of pile with soil under the load of gravitation and load transferring mode along pile shaft for different horizontal pile head loads.
