Abstract

Pile foundation is the most widely used type of foundation foundation in our country, and there are many forms of pile. Compared with other pile types, thread pile has high bearing capacity, strong adaptability, a wide range of application, environmental protection and remarkable economic benefits, so it has been widely used in our country. This paper studies the vertical bearing capacity of spiral anchor pile in silty soil by ABAQUS numerical simulation. The distribution of pile axial force, pile side resistance, pile soil interface stress and soil shear stress around the pile are analyzed. The influence of pile structural parameters is discussed, and the properties of grouting and ungrouting screw anchors in silty soil are studied. The results show that the pile side resistance is larger, the number of anchor disks is 4, and the bearing effect of anchor rod φ140mm is better, which significantly improves the ultimate bearing capacity of single pile.
