The Numerical Calculation Based On ABAQUS Of Lattice Type Steel Sheet Pile Wharf Structure

In recent years, with the development of China’s port industry, good natural conditions of the Bay and the coastal port construction has been developed, the more in a variety of complex conditions, or big waves and rapid flow, or the beach gentle, or foundation in soft soil. The comprehensive advantages of cellular steel sheet pile wharf structure with steel sheet pile and gravity wharf and corresponding limit, which has the advantages of simple structure, can make full use of steel and packing characteristics, so that it can make full use of the characteristics of steel sheet pile high strength, flexural capacity, can fully adapt to the changes, durability strong foundation. However, the lattice structure of steel sheet pile wharf has not been carried out in-depth study, has not established a perfect and reasonable design and calculation method.Therefore, this paper to probe into the application of general nonlinear finite element analysis software ABAQUS on the lattice structure of steel sheet pile wharf is the modeling of single silo structure. And the calculation results are verified with the corresponding theory. The lattice structure of steel sheet pile wharf is the calculation model and rigid model were compared, the steel sheet pile wharf structure of lattice under different conditions is calculated, and analysis, summed up the impact of changes of various engineering factors shape filling soil pressure, structure of steel sheet pile wharf on the lattice displacement lock ring, steel sheet pile to tensile stress.The establishment of calculation model, calculation of steel sheet pile wharf structure of steel sheet pile between hinged on lattice, and the rigid model calculated results, is the innovation of this paper. And, the design is more reasonable on the lattice structure of steel sheet pile wharf with hinge model calculation results.The study found that, when the lattice structure of steel sheet pile wharf and the ratio of height to diameter, the depth reaches a certain value, the lattice structure of cellular steel sheet pile wharf structure in the binding effect of soil stiffness similar to the large diameter and thin shell structure. Through the analysis, the relevant conclusions obtained in this paper can be used as the cellular steel sheet pile wharf structure in practical engineering design reference. At the same time, also provides a research direction in modeling, if further layered soil cohesion, internal friction angle, permeability coefficient, water, groundwater and other parameters, can make the results satisfy the engineering...
