| 摘 要： | 大型围海工程的结构和地基变形控制是设计和施工中的关键和难点问题。采用弹塑性有限元法模拟某大型围海工程的施工顺序和运行工况,进行结构的应力和变形分析。通过计算发现,由于围海结构采用钢筋混凝土高桩和斜坡堤结合的结构形式,而地基为相对软弱的海相软粘土,使得结构的变形成为突出问题,设计时必须对变形和强度稳定进行综合考虑。

| Abstract: | It is an important aspect in design to analyze the strain and stress of construction and foundation of reclamation engineering.Elasto-plastic FEM is employed in the paper to solve the problem,considering the construction procedure and work condition.Deformation became the most serious problem under the condition of reinforced concrete pile with dam and weak ground of marine clay.The deformation shall be considered integrating with the intensity stability. |
