| 摘 要： | 针对港珠澳大桥珠澳口岸人工岛采用吹填砂形成的特点，研究真空联合堆载预压方案和井点降水联合堆载预压方案的可行性。通过对比分析，分别为岛壁区和岛内区推荐了合适的软基处理方案，并根据推荐的软基处理方法对岛内区的地基沉降进行计算。研究成果已成功应用港珠澳大桥珠澳口岸人工岛填海工程的设计。

| Abstract: | For characteristics of the sand filling formation of the artificial island of Zhuhai-Macao Port in the HZMB, this pa- per studies the possibilities of two methods, which are the co-preloading of vacuum and fill method and co-preloading of fill and dewatering method. After comparative analysis, the suitable foundation treatments for the outer and inner part of the island are recommended, and according to that recommended schemes, the ground settlement calculation is made. The results have already applied in the design of sea reclamation projects of the artificial island of Zhuhai-Macao Port in the HZMB. |
