这是一座连接麓湖水城中麓客岛和伊甸岛的步行桥，旨在增强水城的社区组团、公园绿地、商业空间的连接。如柯布西耶所言，自然的秩序在于其中暗含的几何，如同塞尚笔下的风景，用“圆柱体、球体、圆锥体”来表现自然的本质。有别于麓湖水城内其他形态蜿蜒曲折的步行桥，新建之桥要树立一种审美价值，简洁而静谧，以纯粹的几何形式表达柏拉图式的理念（idea）。由此，建筑师选择了三棱锥体（三角形构成的四面体），作为桥的形式母题。

Edenland Pedestrian Bridge connects LuxeIsland and Edenland in Luxelakes, aimed to enhance the connection between the community clusters, parks and green spaces, and commercial areas of the space. While the order of nature, as Le Corbusier perceives, lies in the geometry it contains; Paul Cézanne captured nature through the sphere, cone and cylinder (Paul Cézanne said “Everything in nature is formed upon the sphere, cone and cylinder”). Here the newly constructed Edenland Pedestrian Bridge differentiated itself from other winding pedestrian bridges in Luxelakes with an aesthetic value, simple and tranquil, expressing a Platonic idea through pure geometric forms. Therefore, the architect chose the triangular pyramid (a tetrahedron composed of triangles) as the architectural motif pattern for the bridge.

桥的灵魂在于形式与结构的统一，形式的简洁等于结构的高效。步行桥采用了张拉结构体系,两侧的三棱锥钢架结构是桥身两端的主塔，均以其两角着地成为支点，靠岸端的上角被两侧的抓地拉索下拉固定，驱动这些钢缆，便使连接在主塔面水端上角的拉索中产生了预应力，吊起了另外两个正置的三棱锥，使之悬浮于水面之上。桥面两端通过滑动支座固定于两岸，四个三棱锥所形成的结构托起了长达80米（最大跨度50米）的玻璃步行桥，从而共同形成了整体稳定的结构体系，并产生了“轻盈”之美。

The soul of the bridge lies in the unity of form and structure, in which the form simplicity leads to the structure efficiency. The Edenland Pedestrian Bridge adopts a tensegrity structures: the triangular pyramid steel frames serve as the main towers at each end of the bridge body, with their vertices grounded as anchor points/ fulcrums. The upper vertices of the shoreside are pulled down and fixed by gripping cables on both sides. With these cables driven, prestress is generated within the cables of the upper vertices connected to the water-facing end, suspending the other two upright triangular pyramids above the water’s surface. The two ends of the bridge deck are fixed to both shores by sliding supports, and the structure formed by the four triangular pyramids supports an 80-meter-long glass pedestrian bridge（span 50m）, collectively creating an overall stable structural system and achieving a sense of “lightness” in aesthetics.

为了使结构的几何形态更加的纯粹简洁，三棱锥体的角部定制了分叉的铸钢构件，锥身杆件套插在其分支上，从而构建了纯净而整体的几何形态。桥中间的两个正置三棱锥底部杆件的交叉点落在了桥面的正中心，桥面形态在这一点上顺势变化为菱形，成为水中央的驻足平台。结构是空间的基础，空间的变化是结构逻辑自洽的产物。整个结构体系没有任何冗余的装饰杆件，白色的对称几何框架尽显结构的自明性。

To improve the geometric purity and the structure efficiency, the corners of the triangular pyramids are customized with trifurcated cast steel components, with the rods of the pyramids inserted into their branches, thus constructing a clean and integrated geometric form. In the middle of the bridge, the intersecting bottom rods of the two upright triangular pyramids meet right at the center of the bridge deck, where the shape of the bridge deck center evolves accordingly into a rhombus shape, forming a central standing platform above the water. With structure as the basis of space, the change of space is the outcome of the self-consistent logic of structure. The entire structural system is devoid of any redundant decorative rods, and the white symmetrical geometric frame fully demonstrates the autonomy of the structure.

在技术层面，外荷载、温度作用、预应力，以及人行舒适度等因素，在这个结构体系中被精确地量化，并在隐蔽的位置设置了横向和纵向的调谐质量阻尼器（TMD），进而在优化了结构杆件截面尺寸的同时，保证了整座步行桥的安全和经济。

On the technical level, factors including external loads, temperature effects, prestress, and pedestrian comfort are accurately quantified within this structural system. Horizontal and vertical tuned mass dampers (TMDs) are installed in hidden locations to optimize the cross-sectional dimensions of the structural rods while ensuring the safety and economy of the entire pedestrian bridge.

麓湖伊甸岛步行桥在提供通行的基本功能外，使游人领略到了几何结构之美。它是对自然秩序的另一种表达，与人类的智性相契合。悬浮的几何形体举重若轻，使漫行者感受到绿岛与水天之间的一抹灵韵（genius）。

In addition to providing the basic function of passage, the Edenland Pedestrian Bridge in Luxelakes allows visitors to appreciate the beauty of geometric structure. It is another expression of natural order, echoing with human intellect. The suspended geometric forms handle complicated matters with ease, bringing strollers to sense a touch of genius between the green island, the water and the sky.
