The Finite Element Analysis Of Assembly Embankment Project

With the continuous development of science and technology, Port projects for the construction technology is changing, Recently, a kind of assembly-type embankment technology has emerged, the patented technologies use underwater building units are pre-made on land and assembled on the sea to building the framework, which is late on filled by rubbles. Reducing the engineering load also has the advantages of low cost, fast construction speed and good completion, which is a great value of emerging technologies. But, by the now, there are no comprehensive theories for this technology, under various projects circumstances, the stability of the structure and components of the strength of the engineering requirements also need study. In this paper, to the assembling embankment technology, use the finite element analysis software - ANSYS, considering the construction under various loads, analysis its deformation of the structure and components of the internal forces, for the development of technology in the future and provide the theories.ANSYS software has the power to issue processing, in this paper, use the analysis modal of static analysis, modal analysis, the response spectrum theory, dynamic analysis, and transient analysis Function. Also use the 3-D 8-node module SOLID65 to imitate the concrete, and use the e 3-D 8-node module SOLID45 to imitate the soil, also using the Drucker-Prager to definite the soil parameters. The contractions of the concrete and the soil, use the Targe 170 and Conta173 to definite it.Using the finite element analysis software - ANSYS, and consider the assembly embankment in the wave load, and under the soil pressure, analysis its deformation of the structure and components of the internal forces, get the assembly embankment project's picture of the deformation of the structure and components of the internal forces which under every water level, to Find the weak links in its structure and to improve it.At the same time, the paper also has the seismic analysis, through imposing the earthquake Spectra and Seismic Waves, to analysis the assembly embankment project's transient analysis, get the picture of the displacement of time history and the various components of the stress-time curve.The results showed that the embankment has the advantages of low cost, fast, good quality and other advantages, its structure, the reliability and safety also the same , which show that the assembly of the embankment is a tremendous potential for development New construction technology.
