摘要
为了研究深水软土地基上抛石斜坡堤沉降变形对护面层结构稳定性的影响,采用软土蠕变模型对深水抛石斜坡堤的软土地基的沉降变形进行模拟计算。计算结果表明深水软土地基上抛石堤的竖向沉降和水平变位发展持续时间较长;堤身变形稳定后,堤身中部的竖向沉降量大于堤脚处的水平位移量,堤身外轮廓线长度变短,软土地基和堤身的沉降变形对护面层结构的稳定基本没有不利影响。
In order to study how the structural stability of armor layer is impacted by the settlement and deformation of rubble-mound inclined breakwater on deepwater soft ground, soft soil creep model is used to simulate the settlement and deformation. The calculation results show that the vertical settlement and horizontal deformation of rubble-mound breakwater are of long duration under the condition of deepwater soft soil ground. When the deformation of breakwater reaches stable state, the vertical settlement at the middle of breakwater is more than the horizontal displacement at the toe of breakwater, the external contour of breakwater becomes shorter, and the settlement and deformation of soft soil ground and breakwater almost has no adverse impact on the structural stability of armor layer.
