【 摘 要 】

With the rapid development on the construction of the highways, high-speed railway, large bridges and other large-scale projects, large diameter piles have been widely used in various projects. Based on collecting and sorting the related research literature on the load-bearing characteristics of large diameter pile foundations at home and abroad, the present situation and problems of research on the bearing capacity of large diameter pile foundation are analysed from the theoretical analysis, experiment and numerical simulation, etc. in this paper. Through the study, it was found that there is some difference on the deformation characteristics, mechanical characteristics and law of pile soil interaction between large diameter pile foundation and small-medium diameter pile. At present, the bearing characteristics of large diameter pile theory study still lag behind the engineering application. In particular, the bearing characteristics of contact surface of large diameter pile foundation and the mechanical properties under dynamic loading should be further studied, which will provide certain support for the design and optimization of large diameter pile foundation.
