Background
With the rapid development of economy, buildings such as high-rise buildings, super high-rise buildings and the like are continuously increased, and the pile foundation plays a vital role in the long-term safe use of the buildings. In actual engineering, the pile foundation not only needs to bear vertical load, but also can bear horizontal loads such as horizontal impact load of earthquake load, wind load, water. Therefore, when the pile foundation is studied to bear vertical load and horizontal load, the combined load when the vertical load and the horizontal load act simultaneously, namely the inclined load, is also considered. At present, the research on the pile foundation mostly focuses on the bearing capacity and deformation of the pile under vertical load, and the research on the bearing capacity and deformation of the pile under horizontal load and inclined load is lacked.
At present, pile foundation model test device is mostly vertical loading mode among the foundation engineering of current, and its problem that exists is, and the model test demand of the pile foundation when horizontal load and slope load effect can not be satisfied to single vertical loading mode.
