摘　　要：厦门翔安机场是国内首个建于填海场地的大型机场。从填海造地场地条件、地基处理、桩基础、超长地下结构、耐久性措施以及下穿轨道交通等方面,对T1航站楼基础及地下室设计进行介绍。根据填海造地的特点,设计中需要考虑桩基负摩阻、填海环境下腐蚀性强以及后期地面沉降等不利影响,采取相应的加强措施。结合地勘成果以及基桩试验、沉降分析结果等确定合理的基础设计方案。针对地下超长结构特点,采取了设置延迟封闭U形变形缝等多项抗裂措施。在下穿轨道交通区域,设计柱下独立基础支承于隧道顶板,有效解决了在隧道顶部设置大跨度转换结构时高度不足、造价过高的难题。通过采用轨道减振和局部调整房间使用功能等措施,满足轨道交通引起的振动和噪声的控制要求。Xiamen Xiang’an Airport is the first large⁃scale airport built on reclaimed land in China.The design on the foundation and basement design of T1 terminal building was introduced from the aspects of marine reclamation land site conditions,foundation treatment,pile foundation,super⁃long underground structure,durability measures,and underpass rail transit.According to the characteristics of marine reclamation land,it is necessary to consider adverse effects of negative friction of pile foundations,strong corrosiveness in the reclamation environment,later ground settlement in the design,and to take corresponding strengthening measures.The reasonable foundation design scheme was determined by combining the results of geological survey,pile testing and settlement analysis.In response to the characteristics of super⁃long underground,multiple crack resistance measures such as setting delayed closure U⁃shaped deformation joints had been adopted.In the area underneath the rail transit,the independent foundation under the column was designed to be supported on the tunnel roof,which effectively solves the problem of insufficient height and high cost when setting up a large⁃span conversion structure at the top of the tunnel.By adopting measures such as track vibration reduction and local adjustment of room usage functions,the control requirements for vibration and noise caused by rail transit were met.
