In recent years, with the enhancement of overall national strength in China, the computer simulation technology has been developed rapidly and widely applied to engineering construction. Particularly, investment proportion of the technology in deep foundation pit engineering is immense. Yet affected by national conditions in China, the construction and application of deep foundation pit engineering have many extensive factors. It also results in insufficient vigor of finite element analysis of deep foundation pit support construction. In this way, construction problems arise frequently under the condition that there exist buildings around. With some deep foundation pit support engineering, the thesis conducts simulation analysis of the engineering through the technology of nonlinear three-dimensional finite element.Project profile

Deep Foundation Excavation

The finite element method has been used widely in foundation pit engineering to simulate the deep foundation excavation, but it is troublesome and time-consuming to get the important calculation parameter of the soil elastic modulus. So a method based on the comon soil parameters is proposed to get the soil elastic modulus. And a real foundation excavation was simulated using the finite element software ABAQUS and the soil elastic modulus got according to the proposed method. The three-dimensional finite element analysis results were compared to the field data, and both results were close to each other.

Abstract The effects of variations in stiffness and geometry on the nonuniformity of tires are investigated by using the finite element analysis. In order to evaluate tire uniformity, a three-dimensional finite element model of the tire with imperfections is developed. This paper considers how imperfections, such as variations in stiffness or geometry and run-out, contribute to detrimental effects on tire nonuniformity. It is found that the radial force variation of a tire with imperfections depends strongly on the geometrical variations of the tire.
