Pile Horizontal Bearing Capacity And Its Influencing Factors

Prestressed concrete pipe is an aggregate concrete products of high-tech technology and technological progress in a centrifugal molding technology, pre-tensioned prestressed tensioning technology and autoclave curing technology combined products. Because of its high capacity, high penetration and a wide range of advantages for use in construction projects. Piles of applications become increasingly popular, designers in addition to considering the vertical bearing capacity, the question another common concern is the ability to pile can withstand horizontal loads, this paper pile horizontal bearing capacity and its impact Factors commence the study.Matsubara combined CITIC Bay Project Phase instance, the level of ultimate bearing capacity is determined by the level of pile bearing capacity test, the level of critical load bearing capacity and the level of value; abaqus using finite element analysis simulation software vertical load, pile and pile factor pile bearing capacity of soil properties on the level of influence of the main conclusions are as follows:(1) Capacity test level in prestressed concrete pile, with increasing levels of hierarchical load, pile horizontal displacement and internal forces are increasing.(2) The level of prestressed concrete piles under lateral load-displacement curve with the vertical load combined effect is nonlinear. Overall, the main withstand horizontal loads of prestressed concrete pile stresses, vertical load less impact on the horizontal displacement of the pile in. Because when the next pile in the role of horizontal loads, the horizontal displacement of the pile head to control its level at the main bearing capacity, with piles of concrete strength is generally high, so the level of vertical load bearing capacity of the pile less affected. The numerical simulation of horizontal bearing capacity of prestressed concrete piles under the same experimental conditions, the level can be drawn from the results of the numerical simulation of the bearing capacity test results are basically the same pile, in order to verify the reliability of the numerical simulation.(3) The level of the bearing capacity of prestressed concrete pipe pile pile diameter increases and decreases; prestressed concrete pipe pile horizontal bearing capacity increases as the elastic modulus decreases.(4) Horizontal bearing capacity of prestressed concrete pipe pile soil increases the elastic modulus decreases. Horizontal displacement of prestressed concrete pipe pile with soil cohesion becomes larger and slightly smaller, soil cohesion affect the size of the pile bearing capacity level is not significant; prestressed concrete pipe piles with horizontal displacement the larger soil friction angle slightly smaller, soil friction angle size had no significant effect on the level of the corresponding displacement pile bearing capacity, thus indicating soil friction angle size on horizontal bearing piles are not significant.
