| 摘 要： | 岸坡土体的变形将导致高桩码头桩顶变位，影响桩帽与横梁之间的搭接，使得码头结构处于危险之中，蠕变则是形成土体变形的原因之一。以天津港高桩码头为例，分析了高桩码头的桩顶变位特征，对岸坡土体进行了蠕变特性试验，利用试验结果参数进行了结构与土相互作用的蠕变变形计算。结果表明，蠕变是影响桩基侧向变形的一个重要因素，岸坡土体蠕变主要分布在坡顶下方淤泥质粘土和坡面的淤泥层，蠕变随时间增长而增长，但增长速率降低。相关结论可为天津港和类似高桩码头的检测评估及加固提供指导。 |

| Abstract: | The deformation of bank soil will lead to the displacement of the pile block of high-pile wharf,to influence the joint between the cap-block and the beam,to cause the wharf structures at risk;creep deformation is one of the reasons for soil deformation.Take high piled wharf in Tianjin Port for an example,the deformation characteristics of the pile block of high-piled wharf were analyzed,creep properties test on bank soil was carried out,the deformation computation of the interaction of the structure and soi... |
| Keywords: | soil creep deformation high-piled wharf pile-soil interaction finite element |
