摘要
In this paper,the horizontal bearing capacity of the three-bucket foundation is taken as the research object. Analyze the effect of bucket height,loading angle,loading speed,and drainage conditions on its horizontal bearing performance. The research shows that when the other three influencing factors remain unchanged,as the bucket height increases,the horizontal bearing capacity of the foundation increase. Under non-drainage condition,the loading speed significantly affects the horizontal bearing capacity and the pore water pressure in the bucket. The loading speed under drainage condition has limited effect on the horizontal bearing capacity of the foundation. Under different loading angle condition,the horizontal bearing capacity has doubled. The non-drainage condition can cause the horizontal bearing capacity to increase by 149% compared to the drainage condition. Therefore,in actual engineering,after the sinking three-bucket-foundation,the valve on the bucket top should be closed,which helps to improve the horizontal bearing capacity of the bucket foundation. © 2024 Science Press.
