本项目位于桂林市西南方28公里处的临桂区两江镇，占地面积4.06平方公里，飞行区等级为4E。作为西南地区的一座国际航空港，T1航站楼于1996年建成通航，建筑面积5万平米，可满足年运送旅客500万人次。2015年发改委批复新建10万平米T2航站楼及站坪和陆侧配套设施，以满足2025年航站区1200万人次旅客吞吐量。项目被纳入了广西壮族自治区成立70周年的重点项目名录。

This project is located in Liangjiang Town, Lingui District, 28 kilometers southwest of Guilin City. It covers an area of 4.06 square kilometers and has a flight zone rating of 4E. As an international airport in southwest China, T1 terminal was completed and opened to navigation in 1996, with a floor area of 50000 square meters, which can transport 5 million passengers annually. In 2015, the National Development and Reform Commission approved the construction of a 100000 square meter T2 terminal with apron and landside supporting facilities to meet the throughput of 12 million passengers in the terminal area by 2025. The project has been included in the list of key projects for the 70th anniversary of the establishment of Guangxi Zhuang Autonomous Region.

桂林机场现有一条跑道及一座T1航站楼及其场前配套设施。扩建工程在T1南侧用地新建一座T2航站楼及站坪和场前配套设施。T2航站楼以10万平米的建筑面积提供了年吞吐量850万人次的国内、国际进出港旅客流程。集中式主楼与两条直线型垂直指廊，提供了23~25个近机位接驳条件，挑战了接驳效率的极限,用最少的建设量提供了尽可能多的航空容量，是国内机场航站楼功能效率的典范。五个连续起伏的拱形曲面与进出港大厅—商业或中转连接区域—指廊候机区和到达通廊的空间序列相对应，形成了由主楼到指廊的高—低空间过度，倾斜拱的设计实现了主楼120m的大跨度，整个离港层成为连续无柱空间。竖向分格的超白玻璃幕墙沿建筑立面舒展开。屋顶采用单层拱壳结构，五个高度递减的连续拱覆盖了主要的建筑空间，由多榀互相支撑的倾斜拱为骨架，顶部覆盖单层拱壳结构和屋面构造系统，通过建筑结构一体化精细化设计，实现了结构构件直接成为室内装饰要素。屋面采用双层TPO防水卷材，装饰层采用阳极氧化铝单板，实现了良好的防水性能，并实现了自然真实的金属质感和连续光滑的曲面效果。

Guilin Airport currently has a runway, a T1 terminal, and its supporting facilities in front of the airport. The expansion project will build a new T2 terminal building, apron, and supporting facilities in front of the site on the south side of T1. The T2 terminal provides an annual throughput of 8.5 million domestic and international inbound and outbound passengers with a building area of 100000 square meters. The centralized main building and two straight vertical corridors provide 23 to 25 nearby docking conditions, challenging the limit of docking efficiency and providing as much aviation capacity as possible with the minimum construction volume, making it a model of functional efficiency for domestic airport terminals. The five continuous undulating arched surfaces correspond to the spatial sequence of the entry and exit hall, commercial or transfer connecting area, terminal area, and arrival corridor, forming a transition from high to low space from the main building to the terminal. The design of the inclined arch achieves a large span of 120m in the main building, and the entire departure floor becomes a continuous columnless space. The vertically divided ultra white glass curtain wall unfolds along the building facade. The roof adopts a single layer arch shell structure, with five continuously decreasing height arches covering the main building space. It is framed by multiple tilted arches that support each other, and the top is covered with a single layer arch shell structure and roof construction system. Through the integrated and refined design of the building structure, the structural components directly become interior decoration elements. The roof is made of double-layer TPO waterproof rolls, and the decorative layer is made of anodized aluminum veneer, achieving good waterproof performance and achieving a natural and realistic metal texture and continuous smooth surface effect.

Architecture - Design Philosophy and Technical Strategy

桂林被冠以 “国际性旅游航运枢纽”等众多头衔，本项目作为广西壮族自治区成立70周年重点项目之一，承载了城市新门户和带动经济增长的重大责任。在用地紧张、容量目标压力巨大、与现状衔接难题的背景下，采用单一空侧、贯穿式陆侧及新楼与老楼平行式发展格局，南端开放保留下一期建设灵活性，北端与T1航站楼在空陆侧进行紧密便捷衔接，最大限度节省用地为远期发展预留更大灵活性，并为T1与T2航站楼协同运行提供最大便利。

Guilin has been awarded numerous titles such as "International Tourism and Shipping Hub". As one of the key projects for the 70th anniversary of the establishment of Guangxi Zhuang Autonomous Region, this project bears the significant responsibility of creating a new gateway for the city and driving economic growth. Against the backdrop of tight land use, huge pressure on capacity targets, and difficulties in connecting with the current situation, a single airside, a continuous landside, and a parallel development pattern between new and old buildings are adopted. The southern end is open to the public and retains the flexibility of the next phase of construction, while the northern end and T1 terminal are closely and conveniently connected on the airside and landside, minimizing land use and reserving greater flexibility for long-term development, and providing maximum convenience for the coordinated operation of T1 and T2 terminals.

本项目五个连续起伏的拱形曲面与建筑内部空间序列对应，成对的倾斜拱形支撑实现整个离港层大跨度的连续无柱空间。竖向分格的超白玻璃幕墙沿建筑立面展开，首层采用氟碳喷涂铝单板幕墙。屋顶采用单层拱壳结构以多榀倾斜拱为骨架，，顶部覆盖金属屋面系统，通过建筑结构一体化设计，结构构件直接成为室内装饰要素。屋面创新采用轻型金属屋面与卷材防水和金属装饰板结合的屋面构造系统，实现了结构底板作为装饰板、屋面防水与装饰双层构造等多方面的创新，并申请相关专利，实现了良好的防水性能及自然的金属质感和连续平滑的曲面效果。

The five continuous undulating arched surfaces of this project correspond to the sequence of internal spaces in the building, and the paired inclined arch supports achieve a continuous columnless space with a large span throughout the departure level. The vertically divided ultra white glass curtain wall unfolds along the building facade, and the first floor adopts fluorocarbon sprayed aluminum veneer curtain wall. The roof adopts a single-layer arch shell structure with multiple inclined arches as the skeleton, and the top is covered with a metal roof system. Through the integrated design of the building structure, the structural components directly become indoor decorative elements. The roof innovation adopts a roof construction system that combines lightweight metal roofs with roll waterproofing and metal decorative panels, achieving various innovations such as using structural base plates as decorative panels, and applying for relevant patents to achieve good waterproof performance, natural metal texture, and continuous and smooth surface effects.

The upper roof of this project adopts a steel arch shell structure, with a maximum span of 120m and a maximum overhang of 20m. All support systems are supported by large-span steel arches (there are no structural steel columns in the hall). The central area is supported by a large span arch with opposite inclined directions, and the corridor is supported by a single arch. The direction of the central arch axis rotates with the direction of the roof. The roof steel structure adopts a single-layer grid shell structure, which is arranged in a rectangular manner with circumferential and radial beams for the sake of building aesthetics. The grid shell nodes adopt rigid joints. The transition connection between the supporting arch and the reticulated shell is made by diagonal brace. The thrust and vertical force of the shell roof are transmitted to the arch body through support rods, and the arch and roof components are integrated, with reasonable stress. Consider the performance indicators of support arches, support rods, roof circumferential members, and roof radial members based on the importance of each member. The projected area of the roof is approximately 60000 square meters.
