Model Test Study on the Effect of Vertical Lode on Horizontal Bearing Capacity of Disk Pile

According to the actual work effect of the disk piles，a model test equipment is designed to research load transfer mechanism of the disk piles in different soil layers. No matter in the same or different soil layers，it is proved by test that the increase of the pressure under the disks of the double-disk pile is nonlinear with that of load，and the development of bearing capacity in each disk is not synchro. When in different soil layers，the laws of load transfer of two disks are completely different, the bearing capacities and deformations of the piles with double disks are obviously different.

Test Study

In order to study how it influence the horizontal bearing capacity of the disk pile when there exists a vertical load, a group of model tests has been designed. Three double-disk piles were used in the test, and the distance of the two disks is 5 times as the disk diameter. First drew a vertical load V=200N/300N/400N on the top of pile1/2/3 respectively, then put on the horizontal load stage by stage. And by the test, we can study the differences of the pile bearing properties such as changes in the pile bending moment, the horizontal and vertical deformation on the top. Experiment showed that when the vertical load is quite small（V=200N、300N）, the existence of vertical load has little to do with horizontal bearing capacity. When a vertical load increases to a certain value（V=400N）, The maximum bending moment and horizontal displacement of the pile under the same horizontal load reduce, which indicates that the disks of the pile play a significant role in bearing combined loading.

Behavior Characteristics

The purpose of this study is to grasp the behavior characteristics of a single batter pile under vertical load by performing a model test. The changes in the resistance of the pile, the bending moment, etc. by the slope of the pile and the relative density of the ground were analyzed. According to the results of the test, when the relative density of the ground was medium and high, the bearing capacity kept increasing when the angle of the pile moved from a vertical position to 20°, and then decreased gradually after 20°. The bending moment of the pile increased as the relative density of the ground and the batter angle of the pile increased. The position of the maximum bending moment came closer to the ground surface as the batter angle of the pile further increased, and it occurred at a point of 5.2~6.7 times the diameter of the pile from the ground surface.
