| Abstract: | The actualities and characteristics of the numerical simulation of reinforced concrete are discribed; and the advantages and disadvantages of numerical model and its applicable condition are introduced too. The main methods to use the finite element method, including unit mode, transfer mechanism and numerical method are reviewed. And then its causes and main influential factors are discussed; the general principle and method of the practical application are summarized; and the research direction of numerical simulation of hy- draulic reinforced concrete in the future is proposed. |
| Keywords: | hydraulic structure reinforced concrete crack simulation finite element numerical analysis |
