Study On The Interaction Between Inland River Suspended Vertical Frame Wharf And High-Cut Bank Slope

Nowadays,inland river frame wharf is used widely in harbor engineering, enormous economic benefits, social benefits and environmental benefits were obtained. Nevertheless, the deformation behaviour and working mechanism of Inland River Suspended Vertical Frame Wharf have not well understood and rational analysis theory and design methods for these structures are not available. The theoretical study cannot fulfill the rapid and wide requirements in engineering design and construction. Moreover, the developing of the numerical analysis methods and computer simulation technology, as well as the complexity of the interaction itself, the field of the interaction has become the focus of attention problems. Therefore, the interaction study of the Inland River Suspended Vertical Frame Wharf is obviously significant on the structure and foundation design.This paper summarizes the research methods and results of the interaction effect between the structure's upper part of the and foundation , in view of the characteristics of the frame wharf high fill and weak interlayer, and I take the an engineering Container Terminal Cuntan as background, set up the generalizability the joint effect calculation model of the river terminal overhead vertical frame structure and high and steep slope, which considering the construction process and interaction effect, and use the large-scale finite element software,take the three-dimensional simulation analysis in the model to get the displacement in the upper part of the structure, foundation and bank foundation, stress change, as well as the stiffness of the joint effect of change on all sides, and the problems for the optimization of the proposed structure. Through the construction sequence in different conditions, comparaing the analysis of shared the role in framework port and the bank , put forward a reasonable construction sequence framework for river trade terminal overhead vertical:the first pile and ground beam or the formation of a layer of the framework to arise the overall scheduling frame, and then backfill the foundation, then backfill construction the framework of the upper structure and the banks synchronous to the design elevation, and finally access to offshore structure construction. At the same time, for the questions in terminal high fill slope weak interlayer,use the strength reduction FEM to analyse,get the failure mode terminals of banks, and advance a strengthening method considering a common role , at the same time, proposed amendments to soil strength reduction coefficient, provides a reference for the effect of introducing a interaction analysis method to guide the actual project and problem-solving.
