Numerical Simulation of Double Row Piles Prestressed Anchor Cable Support Based on ABAQUS

With the development of urban construction, there are more and more high-rise buildings, and excavation support methods have emerged. Traditional support methods have the drawbacks of a small range of safety factors and high economic requirements. Based on this, this article proposes a new type of support method using double row piles and prestressed anchor cables, and establishes a numerical model using ABAQUS software. The results indicate that: (1) As the excavation depth increases, the horizontal displacement of the foundation ditch continues to increase, and the displacement of the piles also continues to increase. (2) After soil excavation, there is a bottom bulge phenomenon at the bottom of the foundation ditch, and the piles move upwards, causing the soil around the foundation ditch to decrease.
