Abstract

Based on the physical test and finite element calculation method, the construction effect of mono-column composite bucket foundation in engineering application is analyzed, and the top-bearing mode of mono-column composite bucket foundation is summarized. The effective method to improve the bearing capacity of shallow bedrocks is proposed based on its bearing characteristics. The results show that： the influence of construction effects gradually weakens during the cyclic loading process. The bearing capacity of mono-column composite bucket foundation is mainly exerted by the top cover, the simulation of ultimate bearing capacity using equivalent gravity model can better reflect the bearing characteristics of mono-column composite bucket foundation, and the calculation of mono-column composite bucket foundation can be simplified through equivalent gravity model. It can be seen that ballast can effectively improve the applicability of mono-column composite bucket foundation in shallow bedrocks.
