Abstract
In order to study the influence of the arrangement of pull-out piles on the internal forces,deformations and pull-out pile reactions of the subway station main structure of the floor and bottom longitudinal beam,and choose a reasonable arrangement of pull-out piles,the anti-floating design of a large-section subway station in a coastal city was taken as the engineering background.The three-dimensional finite element calculation of the main structure of the station under six different arrangements of pull-out piles was carried out by using midas Gen finite element analysis software.By comparing the calculation results of six different arrangements of pull-out piles,it is shown that the arrangement of pull-out piles in the middle span of the bottom longitudi-nal beam can effectively reduce the internal force of the bottom longitudinal beam.At the same time,for the large-section station,in order to meet the requirements of the anti-floating stability of the station and the de-sign bearing capacity of the pull-out piles,small diameter pull-out piles can be used to densely arrange the middle span area of the station floor.Under the requirements of the internal force and deformation of the sta-tion floor structure,good economy can be obtained.关键词
