The theory of plates and shells is not adapted to design thickness for the multi-holes plates in engineering. A new method to quickly optimize the thickness based on the finite element method theory was put forward. The method combined the theory of plate with the finite element method to establish a mathematical model and analyzed the influences of load, constraint and complexity on design error. The practices demonstrated that the proposed design method is effective and feasible.

This paper presented the result of analysis about R/C arch by use of finite element method. The design method for R/C shell has not been established due to its numerical difficulties. Using the finite element method, it was possible to analyze these structures. However, the precise experiments were required to verify the reliability of these analyses and it was necessary to improve the numerical analyses. An R/C arch is a basic form of the R/C shell. Under various conditions, that was, R/C arch without initial imperfection, different rise-span ratio, three types of loading points and supporting conditions, loading tests of R/C arch were performed. After experiment, analysis was also carried out. And as the result compared experimental and numerical results, accuracy of this analysis method was elucidated.

At present, the widening highway retaining wall is often used in engineering practice, but compare to the new highway retaining wall, there is not any highlight differences on design method to the widening highway retaining wall. The paper lays on a widening highway retaining wall in an engineer, based on the analysis of the differences between the widening highway retaining wall and the new highway retaining wall, using the finite element method for modeling and analysis of the widening highway retaining wall and the new highway retaining wall, then conclude that the soil displacements and earth pressures between the two models are significantly different, finally point out the considerations in design.
