摘要：

According to the land formation project of Shenzhen Marine emerging industry base, the influence of three kinds of reactor preloading, vacuum preloading, on the adjacent pile foundation at different distances is studied by two-dimensional finite element analysis method. The results show that (1) the closer the pile foundation is to the preloading construction area, the greater the overall deformation; the influence of reactor preloading treatment on the horizontal deformation of adjacent pile foundation is much greater than vacuum prepressing treatment and vacuum combined preloading treatment; the influence range of reactor preloading treatment on adjacent pile foundation is greater than that of vacuum preloading treatment and vacuum combined preloading treatment.(2) The closer the pile foundation is to the prepress construction area, the more the bending moment is affected; the influence of the combined preloading treatment on adjacent pile foundation is much greater than that of vacuum prepressing treatment; and the influence of the preloading treatment on combined pile foundation is greater than that of vacuum prepressing treatment on adjacent pile foundation.
