| 摘 要： | 沉管隧道纵断面结构计算常采用弹性地基梁或弹性地基板法,但这些方法较难真实模拟沉管隧道的受力情况,特别是接头的受力情况。文章以三维实体单元出发,引入适当的假设,对沉管隧道静力作用下的受力、位移,特别是接头受力情况进行了详细的模拟分析,对沉管隧道结构纵向计算做了有益的探索,对类似工程有较强的指导意义。

| Abstract: | Immersed tube tunnels are often analyzed by using the method of beam or plate on elastic foundation which can not precisely simulate the behavior of joints.This paper adopted three dimensional elements,with suitable suppositions,to study the stresses,displacements,especially the behavior of joints and to carry out detailed simulation analysis and structural analyses in longitudinal direction of immersed tube tunnels.Results of the analyses possess beneficial instruction significance to similar projects. |
