    摘要:

    针对深厚软土地基及堆载作用的复杂条件, 采用装配式钢圆筒护岸结构, 开展结构稳定及变形分析。首先确定合理的结构方案, 并通过条分法分析护岸整体稳定性, 其次采用数值模拟法分析钢圆筒在堆载作用下的变形特性, 最后通过离心模型试验验证装配式钢圆筒护岸的可靠性。结果表明:在深厚软土地基条件下, 利用深插式钢圆筒截断堆载作用下的深层滑动面, 保障护岸的整体稳定;当堆载作用距离护岸轴线120 m时, 钢圆筒顶部位移约10 cm, 筒体向海侧倾斜0.09°。通过堆载距离的控制, 其作用下钢圆筒变形对重要建筑物结构影响较小, 为钢圆筒护岸建设提供理论支撑。

    Abstract:

    In view of the complex conditions of deep soft soil foundation and loading effect, this paper analyzes the stability and deformation of a prefabricated steel cylinder revetment structure.Firstly, the paper determines a reasonable structural scheme and analyzes the overall stability of the revetment through the slice method.Secondly, the paper adopts a numerical simulation method to study the deformation characteristics of the steel cylinder under loading effects.Finally, the paper verifies the reliability of the prefabricated steel cylinder revetment by a centrifuge model test.The results show that under the condition of a deep soft soil foundation, the deep sliding surface under loading effects can be truncated by a deeply inserted steel cylinder to ensure the overall stability of the revetment.The top displacement of the steel cylinder is about 10 cm, and the cylinder tilts to the seaside by 0.09° when the loading effect is 120 m away from the revetment axis.By controlling loading distance, the deformation of the steel cylinder under loading effects has a slight influence on the structure of important buildings, which provides theoretical support for constructing steel cylinder revetments.
