Abstract
In order to reveal the mechanical deformation mechanism of adjacent single pile foundation caused by foundation pit excavation,this paper takes a foundation pit project as an example and constructs a numerical model to deeply study the influence of excavation disturbance on horizontal displacement,shear force and bending moment of adjacent single pile foundation structure.The results show that when the pile top is free,the horizontal displacement of pile foundation decreases with the increase of pile length.The bending moment in the pile body increases first and then decreases with the increase of pile length,and the shear force increases first and then decreases with the increase of pile length in a"Z"type evolution trend.When the pile top is a fixed end,the deformation of pile foundation increases first and then decreases with the increase of pile length.With the increase of pile length of single pile foundation,the bending moment in pile body increases first and then decreases.With the increase of the excavation depth of foundation pit,the shear force in pile body decreases and changes to negative shear near the excavation face of foundation pit.Therefore,it is necessary to strengthen the monitoring and deformation control measures for the deformation of single pile foundation near the depth of foundation pit.关键词
