Research Of Disposal Project On The Complex Groundsill Foundation About Zhuzhou Navigation And Electricity Junction

Because of the ground defection, foundation treatment of maritime structure based on the complex foundation will influence security and stabilization of upper structure. Therefore, it is the key to the security and stabilization of whole structure to research the scheme of foundation treatment and determine the reasonable model of foundation.Based on the sluices project of Zhuzhou Navigation and Electricity Junction, and adopting nonlinear finite element theory, the mathematical model is proposed to simulate the elastic and plastic character of concrete and soil material. Assisted by the FEM software-ANSYS, it compares the arch project with pile groups-cap project, analyses sluices foundation which embody weak intercalated layer, and analyses the effect of treatment to weak intercalated layer on the sluices structure.Firstly, the arch foundation project of foundation treatment is calculated and its effect on sluices structure is analyzed. The treatment effects with different design parameter of arch show that the arch foundation project products excessive sedimentation and structure stress damaging the structure.Secondly, analyses the pile groups-cap project, researching on the effect of pile groups-cap project, through compared with the arch project, the pile groups-cap project could improve the structure's function. Sedimentation and stress of upper structure is decreased, the pile groups-cap project is better than arch project.Thirdly, the mechanical character is analyzed of the short—long piles composite foundation model under two work conditions, which shows great influence of the level force on maritime structure.Finally, the effect on sluices structure of the ground embody weak intercalated layer is analyzed, which shows that the treatment has great influence on whole structure.The conclusion from this paper can be referred to design and construction of similar projects.
