| 摘 要： | 大直径钢圆筒已在国内外港口、跨海桥梁等工程中应用，但对于大直径钢圆筒的变形特性认识依然不足。基于国家科技支撑计划项目依托工程——港珠澳大桥东人工岛岛壁结构-钢圆筒的深层水平位移实测资料，结合数值模拟，对大直径钢圆筒变形特性进行探讨。实测资料和数值模拟结果表明：钢圆筒结构随着筒内土体固结程度，其变形特性近似于重力式结构。

| Abstract: | The large-diameter steel cylinders are applied to harbor and sea-crossing engineering.But there is still a lack of grasp of the deformation characteristics of the-large diameter steel cylinders.Based on the measured data of the East Artificial Island of Hong Kong-Zhuhai-Macau bridge,we carry out the study on it.The result reveals that with the soil consolidating in the cylinder,the deformation characteristics of the steel cylinder is similar to that of the gravity structure. |
