The Finite Element Analysis Of Pile Groups Subjected To Lateral Loads

At present,there are many research methods on pile groups subjected to lateral loads at home and abroad. However,it is still far from meeting the demands of pile groups appliances in engineering.Using the finite element software ANSYS,the article calculates and analyses the behavior capacity of pile groups first. It discusses the influence factors of pile groups effect,such as pile space,pile number,pile diameter,pile length and soil parameter etc.Subsequently,using linear interpolation function to approximate the soil's anti force to piles,the article combines p-y curves with pole system FEM. In this way,a new pile-soil interaction element calculated model is designed,the pile-soil interaction element stiffness matrix is deduced,and establishes finite element equation of p-y model,writes the relevant finite element program with MATLAB language,calculates and analyses pile groups subjected to lateral loads with engineering examples.
