| 摘 要： | 采用有限元软件PLAXIS来计算分析箱筒型基础防波堤结构的沉降变形,将箱筒型基础结构用线弹性模型模拟、地基深层土用摩尔-库仑模型模拟、表层和浅层软土用蠕变模型模拟,并考虑了结构和软土间的接触界面,沉降变形的计算结果与实测结果符合较好,表明利用PLAXIS软件采用这些模型计算的箱筒形基础结构的沉降变形结果是可靠的,计算分析表明,软土地基采用箱筒形基础能有效减少预留沉降量。

| Abstract: | The finite element analysis software package, PLAXIS is used to analyze the settling deformation of the breakwater with box-type suction foundation in the paper, in which case the box-type foundation structure is simulated with a linear-elastic model, the deep soil with a Mohr-Coulomb model, and the shallow clay with a soft-soil-creep model, with the interface between the structure and clay taken into account, and the calculated results of the settling deformation of which are in good agreement with the measured results, and therefore are proved reliable. As a result, it may be concluded that a box-type suction foundation used in soft soil can effectively reduce the reserved settlement. |
