Wuhan-Shiyan High-speed Railway (from Wuhan to Shiyan) is 399km long, with 12 stations along the line, connecting Wudang Mountain, Gulongzhong, legendary emperor Shen Nong’s hometown, Yellow Crane Tower and other famous tourism spots. The tourism revenue of this region, so-called the tourism high-speed railway with the most beautiful landscape in Hubei, accounts for 70% of that of Hubei Province. With the opening of the Wuhan-Shiyan High-speed Railway, the distance between Wuhan to Suizhou will be shortened to 50 minutes only. The high-speed railway provides an unprecedented opportunity for the urban development of Suizhou, especially for the tourism. As a destination of tourism spot, the station will also become an important icon to present the local uniqueness.

表达地域环境特色
The characteristics of regional characters

随州洛阳镇的千年银杏谷，是世界四大密集成片的古银杏聚落之一。每逢中秋时节，银杏树下，金叶纷飞，成为了旅游者心中的世外桃源。我们从中获得启示，树状结构体系营造出森林一般的空间，挺拔的树状结构与动态屋面发生最直接的视觉关联，清晰地表达结构传力的逻辑。因此在随州南站的设计中，我们从表现城市地域特征的角度，将“银杏树下” 的自然意境融入建筑，让旅客获得独特的空间体验。

The Millennium Ginkgo Valley in Luoyang Town is one of the four ancient ginkgo landscapes in the world. During every Mid-Autumn Festival, the golden leaves fly around the ginkgo trees, becoming a paradise in the eyes of tourists. Hence, we follow tree structural system by creating a forest-like space. The straight tree structure has the most direct visual connection with the dynamic canopy, and clearly shows the logic of structural force transmission. Therefore, in the design of Suizhou South Railway Station, we integrate the natural artistic feeling of “under the ginkgo tree” into concept design from the perspective of presenting urban regional characteristics, so that tourists can get unique space experience.

树状结构与空间营造
Tree structure and space creation

我们通过对银杏叶片的抽象与重构，得到了构成空间的基本“叶片单元”。每个单元尺度为27X24米，覆盖面积约648平方米，采用24个完全相同的叶片状单元体建构成站房主体空间。在实施程中我们进行了优化：每4个小单元屋面分组合并，形成六组连续的曲面屋顶，结构更为合理，同时也降低了建造难度，有利于控制建造成本。这样，富有韵律的自然曲线，轻盈灵动的建筑形体，使得建筑内外空间浑然一体。叶片状单元体集建筑、结构、采光于一体，光线透过薄膜将内部构造徐徐展现，犹如树叶纹理，隐喻自然，体现结构之美。

Through the abstraction and reconstruction of ginkgo leaves, we get the basic “leaf unit” that makes up space. The dimension of each unit is 27 x 24 meters, covering 648 square meters. The main space of the station is composed of 24 identical leaf-like units. Also, we optimized further during implementation: every four small roof units are grouped and converted into six groups of continuous curved roofs. The structure is more reasonable, construction difficulty is lessened, while construction cost is reduced in the meantime. Thus, the rhythmic natural curves and the light and flexible architectural structure can be integrated into the internal and external building space. The leaf-like unit consists of architecture, structure and lighting. The light reveals gradually the internal structure through the film, just like the leaf texture, which metaphors the nature and embodies the beauty of structure.

室内外光环境
Indoor and outdoor lighting

车站室内光环境的舒适性也是我们考虑的重要因素。单元体顶部设有采光天窗，通过透光膜的过滤产生柔和的漫射光，避免了眩光和阳光直射，室内照度也更均匀。我们通过照明模拟计算确定天窗面积，使得候车大厅在白天即使是阴天都可满足照度要求。阳光透过顶部天窗洒落在“叶片”单元体腔内，光线漫射形成一个个金色发光体，营造出“银杏树下，金叶纷飞”的空间意向，完美展现了叶片温润、通透的质感。自然光线引入，使建筑空间生动而富有生命力。夜间则通过设置于透光膜腔体内的 LED 灯点亮形成发光体，传达出中国传统 “灯笼”意蕴，进一步增强了车站的标识性和引导性。

The comfort of indoor lighting is also an important factor. A skylight on the roof produces soft diffuse light through the filtration of transparent film, avoiding glare and direct sunlight, and the indoor illumination is more uniform as well. We determine the dimension of skylight through lighting simulation calculation, so that the waiting hall can meet the illumination requirements in the daytime even when it is cloudy. The sunlight shines through the top skylight into the “leaf” units, and become goldenly luminescent caused by the light diffusion, creating the spatial intention of “golden leaves fly around under the ginkgo tree”. It perfectly shows the warm and transparent texture of the leaves. The introduction of natural light makes the architectural space vivid and full of vitality. At night, they will be lighted by the LED lamps inside through transparent films, which conveys the meaning of traditional Chinese “lanterns”, and further enhances the symbolism and instructiveness of the station.

新材料与新工艺
New materials and new technology

这种空间效果的形成，关键在于覆盖在单元体外侧的ETFE膜材的性能。我们确定75% 的透光率、漫反射、金色这三个基本要素。我们几乎找遍了全球的供应商，在最后关头，德国ETFE膜材生产商答应为我们定制这种材料。ETFE膜材拥有良好的耐久性、阻燃性及透光性能，但是对拉力和温度变化较为敏感，为保证“叶片”最终形成饱满、光滑的曲面形态，项目团队需要对索网系统和膜材的张拉有着极其精准的控制。我们和施工单位一起联合大学科研团队，深入研究膜材力学性能及索膜受力体系专项技术，依托BIM及3D现场扫描技术，对相关节点及构造进行了多处优化创新，形成了一整套技术措施，精准完成 “叶片”各部分组件的设计与安装。

The key to the formation of this spatial effect is the performance of the ETFE film covering the outside of the unit structure. We determined the three basic elements of 75% transmittance, diffuse reflection and golden color, and had looked for suppliers all over the world. At the last minute, German ETFE film manufacturers agreed to customize this material for us. ETFE film material has good durability, flame retardancy and light penetration, but it is sensitive to tension and temperature changes. In order to ensure that the “leaf” finally forms a plump and smooth curved surface, the project team needs to have extremely accurate control on the tension of cable net system and film material. Together with the construction company and the university research team, we did an in-depth study on the mechanical properties of film materials and the special technology of cable film stress system. Relying on BIM and 3D field scanning technology, we optimized and innovated the some parts and structures, developed a whole set of technical measures, and accurately completed the design and installation of various components of “leaf”.

高舒适性的空间体验
Highly comfortable space experience

当你乘车来到随州南站的高架落客平台，仿佛置身于银杏树的丛林，这个挡风遮雨的车站半室外空间会给你留下深刻印象。当你走进随州南站，令人舒适的柔和均匀的天然光线透过“银杏叶片”散发出来。候车大厅非常安静，语音广播格外清晰，没有火车站常见的噪音困扰，这得益于表面积超过1万平方米单元体的膜材所具有的良好的吸声效果。

When you come to the railway entrance of Suizhou South Station on the highway by car, you will feel you are in the forest of ginkgo trees. You will be deeply impressed by the semi-outdoor space of this well-sheltered station. When you walk inside the Suizhou South Station, the gentle, diffuse and comfortable natural light penetrates from the “ginkgo leaves”. Due to the good performance of sound absorption effect brought by the film with surface area more than ten thousand square meters, the waiting hall is very quiet, and the broadcast is exceptionally clear without the common noise distraction like other train stations have.

最终，“银杏叶片单元体”成为了整座建筑中令人印象最深刻的部分，富有韵律的结构单元，柔和的光线、温润的质感，模糊了人工与自然的边界，诠释着崇尚“天人合一”的东方传统哲学思想。

Eventually, the “ginkgo leaf unit” has become the most impressing part in the entire building with rhythmic structural unit, soft light and gentle texture. It blurs the artificial and natural boundary, and illustrates the profound eastern traditional philosophy of “unity of man and heaven”.
