Study on Load Bearing Characteristics of Soft Soil Foundation Building Pile Foundation
In order to improve the bearing capacity of pile foundation of soft soil foundation,this paper takes a building pile foundation in Guangdong as an example,and analyzes the bearing characteristics of single pile and pile group by using experimental model method.The re-sults show that when the pile top load is 0.6 kN,the pile top settlement is 10 mm,which is 9 times higher than that when the pile top load is 0.25 kN.The axial force of pile decreases with the increase of pile depth.With the increase of pile top load,pile tip resistance is stable at first and then rapidly increases.The larger the inclination Angle,the smaller the settlement of pile top,the larger the axial force of pile body and the smaller the resistance of pile end.With the increase of load level,the axial force of pile body under the same pile depth increases con-tinuously.
