The Impact Analysis of Slopes Thin-wall Pipe Pile Structure Parameters on the Mechanical Properties Based on the Coupling Action of Piles and Soil

On the slope structures,due to the changes of Shan Po Po potential,foundation under horizontal load. Using the theory of pile foundation under horizontal load,the structure of a building on the pile and soil under horizontal load force mechanism of the mutual coupling effect and performance research,and to establish a finite element model of slope pipe pile under horizontal load,by changing the pile stiffness,diameter,wall thickness,pile length,structure parameters,such as under the action of the pile in the pile-soil common working condition to carry on the numerical simulation,study the stress of the slope when the thin wall pipe pile under horizontal load,deformation regularity,the results show that under horizontal load,the displacement of the top of the pile of the largest,and the horizontal displacement and decreases with the increase of soil depth,when the pile reaches a certain depth,displacement values appeared a turning point,pile bottom a built-in function; Pile bending moment along with the elastic modulus increases with increasing pile length,diameter,and decreases with the increase of the pile body wall thickness. For the greatest influence of horizontal displacement of pile pile elastic modulus,pile length,diameter,and wall thickness has no effect on horizontal displacement of pile is basic; the horizontal displacement of the pile decreases with the elastic modulus、diameter and pile length's increasing.
