英文摘要For the pile foundation subjected to both horizontal and vertical loads, the horizontal and vertical bearing capacities are often calculated separately according to existing methods, and the influence of the vertical loads on the horizontal bearing capacity of the pile is not considered. Several model tests were carried out for the horizontal loaded pile to study the horizontal bearing behavior of pile under the action of existing vertical load in sandy foundation. In order to avoid imposing additional constraints on the pile top under vertical loads, the selfdesigned test loading device was developed for vertical loading, and the thin film pressure sensor was used to accurately measure the horizontal soil resistance. The test results show that: in sandy soil foundation, vertical loads applied in advance reduces the horizontal displacement and bending moment of horizontal loaded pile in some segments. The maximum value of horizontal soil resistance first increases and then decreases with the increase of existing vertical load. The horizontal bearing behavior of the small-diameter preformed pile can be improved by the vertical load in sandy soil foundation when the horizontal displacement is small.
