呼伦贝尔海拉尔机场位于内蒙古呼伦贝尔市海拉尔区，以世界最美草原、十佳冰雪城市的美誉享誉全国。原T1航站楼建筑面积7600㎡，为了解决日益增长的草原旅游需求带来的旅客流量激增，需要扩建现有航站楼。

Hulunbuir Hailar Airport is located in Hailar District, Hulunbuir, Inner Mongolia. Hulunbuir is well known as one of the Top 10 Snowy Cities in China with its most beautiful prairies in the world. The built-up area of existed T1 Terminal was 7,600 m2. It could not meet the need of ever-growing passenger volume for prairie tourism. Obviously, it is necessary for the existed terminal to be expanded.

设计之初，建筑外轮廓、平面流线都已通过评审确定，如何在限定条件下，打造既具有时代感、又兼具浓郁地方特色的门户航站楼建筑，成为设计最大的挑战。

At the beginning, the boundary and plan of this expansion project were fixed. As a result, we were facing a great challenge – how to design a modern architectural work with rich local features by the fixed conditions.

设计引入独特的结构形式，框架柱在二层呈双V形斜撑支撑屋面。柱、吊顶、屋面结构有机结合，消融垂直界面与水平界面的界限，营造如蒙古大帐一般连绵、贯通的空间感受。金色、白色的主色调使人仿佛置身于洒满阳光的白桦林间。

An innovative architectural form was produced – frame columns support the huge roof on the second floor by several double-V-shaped diagonal structures. The boundary between vertical and horizontal interfaces is eliminated by the structural integration of columns, ceiling and roof, to create a continuous Mongolian-yurt-like space. This golden and white huge space also makes people feel like they were in the sunny birch forest.

形态上采取南高北低的策略，陆侧形成通高檐下空间。双向波浪式单层网壳屋面的曲面造型呼应典型的草原文化地域特征——白云、羊群，使到达机场的使用者无论从云端还是路上都能感受到T2航站楼连绵起伏、富有韵律及层次感的特色形态。

An under-eave space with double-height is created in the landside system by the altitude difference designed between the south and north facades. Clouds and herds, the typical local elements, are beautifully expressed by the elegantly curved roof with bi-directional single-layer reticulated shells. A broad undulating and rhythmic view is shown to the passengers in everywhere of this layering T2 Terminal space.

绵延的雨棚成为连接新老航站楼的重要元素，形成统一建筑语言，加强了新、旧航站楼前车道和等候空间的贯通性，创造了怡人尺度的室外灰空间。

The stretching canopy is an important element connecting the new and old terminals. A unified architectural language is produced by this perfect connection. Also, the space connectivity is achieved between the front driveways and rear waiting spaces in the two buildings, creating a pleasant under-eave space.

考虑到建造难度，将纵向7跨的航站楼的主体结构、屋面、内装整合成两跨的基本单元。以屋面网架结构的尺寸作为基本模数，对铝板的曲率、曲面进行分析和归类：曲率较小的简化为平面铝板，曲率略大的简化为单曲面铝板，极少数曲率较大的为双曲面铝板，进而将工艺难度和造价控制到最低。

The main architectural structure, roof and interior of the planned vertical 7-span terminal building are integrated into two basic spans to decrease the difficulty of construction. Taking the size of roofing grid structure as the basic modulus, aluminum plate is analyzed and classified by its curvature and camber: the plate with less curvature is used as the flat, the plate with more curvature as the single-curved, and some with typical curvature as the double-curved, to minimize the construction difficulty and cost.

在后期深化设计与建造过程中，我们创新性地深化异形龙骨幕墙、TPO屋面、双曲铝板开花柱节点，并采取异地1:1放样的方式调整、确保实际建造效果。

Shaped keel curtain wall, TPO roof, and nodes of flowering column made by double-curved aluminum plate are innovatively deepened in the post-deepening design and construction process. And the 1:1 model was set to do some adjustment, so as to ensure the actual construction effect.

呼伦贝尔海拉尔机场作为呼伦贝尔面向世界的窗口，我们希望能赋予T2航站楼国际先进的机场建筑特色与地方深厚的本土意蕴，让她成为带动草原旅游业发展的枢纽工程和城市名片，成为一颗轻盈、纯洁、璀璨的草原明珠。

Hulunbuir Hailar Airport serves as the first landmark for visitors to Hulunbuir. Hence, the T2 Terminal is designed with strong local features and all the basic architectural elements an international advanced airport needs. It is a key project to promote the development of prairie tourism. It is a brilliant pearl on the prairie.
