【Abstract】 Taking the wall structure of Guigang Shiplock as an example, the paper describes the basic principle of finite element analysis on large size cement concrete structure by using SAP5 program. Besides, by linking with ViziCAD program before or after the finite element analysis, the paper also provide the description on the modeling, unit division, load adding, restrict calculation analysis and treatment methods after analysis etc.. At the same time, it introduces the analysis result on stress and wall top displacement during the design of shiplock structure modification and construction, which has good effects. The shiplock has operated safely for years, this shows that the design of shiplock structure is reasonable, the overall stability is quite good and the construction quality is satisfactory.更多还原
