大理喜洲万花溪1号桥丨中国大理丨ORS Studio

云南第一座改性混凝土3D打印步行桥在大理喜洲万花溪畔落成。这座步行桥位于大理喜洲生态廊道的关键节点，属于喜洲慢行交通系统的一部分。设计在保留原石板桥场所记忆的基础上进行了轻量化改造，以独特的数字化混凝土语言，将生态理念与地域文化凝为一体，让前沿技术浸润日常景观，展现出数字建造赋能乡土场景的可持续路径。

The first modified concrete 3D-printed pedestrian bridge in Yunnan was recently completed on the banks of Wanhua Stream in Xizhou, Dali. Situated at a critical node of the Xizhou Ecological Corridor, the bridge forms part of the local slow-traffic network. The design adopts a lightweight transformation approach while preserving the spatial memory of the original stone slab bridge. Through a distinctive digital concrete architectural language, it integrates ecological concepts with regional culture, allowing cutting-edge technology to permeate the everyday landscape. This project demonstrates a sustainable pathway for digital construction to empower rural contexts.

项目需在一座既有旧桥的基础上进行改造升级，现状条件极为复杂。原桥存在明显的高低差且桥体并不垂直于两岸；另外现场施工场地十分狭窄，作业空间严重受限；加之雨季湿度高、昼夜温差大，材料易受胀缩影响，进一步增加了工程实施的技术难度与施工上的不确定性。▼现场施工，On site operation ©和畔皓森文化旅游投资有限公司

The project involves the renovation and upgrading of an existing old bridge under highly complex site conditions. The original bridge exhibits significant elevation differences and is not perpendicular to the banks. Furthermore, the construction site is extremely narrow, severely limiting operational space. Additionally, high humidity during the rainy season and significant diurnal temperature variations increase the risk of material expansion and contraction, thereby amplifying technical challenges and construction uncertainties.

为应对复杂现状，团队引入3D扫描技术对原石板桥进行了高精度的测量，以确保每一块3D混凝土打印模块能在现场准确放置。施工中每出现一处误差都会回传至数字模型进行实时调整，并通过多次三维扫描、模型比对与反馈修正，将误差收敛至现场施工的允许范围内。▼爆炸图，Exploded axonometric diagram ©和畔皓森+ORS Studio

To address the complex existing conditions, the team employed 3D scanning technology to conduct high-precision measurements of the original stone slab bridge, ensuring the accurate on-site placement of each 3D concrete printed module. During construction, any deviations detected were relayed back to the digital model for real-time adjustments. Through multiple iterations of three-dimensional scanning, model comparison, and feedback-based corrections, all errors were systematically reduced to within the permissible tolerance for field construction.

使用3D混凝土打印技术，喜洲万花溪1号桥的设计解构了传统步行桥，将踏步、栏板与扶手融为一体，成为了一道可踏、可坐、可倚、可扶，亦可桥上远望的景观。设计不仅重新处理了功能性上的两岸连接、上桥高差、行走安全及结构安全等问题，同时以流畅的造型赋予了其美学意味，其形态如同花瓣上的每一道转折，为万花溪增添了一朵新“花”。

Employing 3D concrete printing technology, the design of Xizhou Wanhua Stream Bridge No.1 deconstructs the traditional pedestrian bridge by integrating steps, parapets, and handrails into a unified form. This creates a landscape feature that is walkable, seatable, leanable, grippable, and also serves as an exceptional vantage point for distant viewing. The design not only addresses functional requirements such as riverbank connectivity, elevation changes, pedestrian safety, and structural integrity but also endows the bridge with aesthetic significance through its fluid morphology. Its form, evoking the delicate folds of petals, appears to bloom along the Wanhua Stream.

在地的、轻量化、快速的，是项目的技术主旨。1号桥在打印的混凝土中掺入了40%的固废掺合料，以邻近建筑工地的砖渣和磷石膏作为骨料纳入打印油墨，实现了资源的节省与就地循环利用。所有构件均在地打印，无湿作业与模板工程，施工周期极短。从数字模型到实体建筑，全程贯彻“所见即所得”的精准控制，确保设计意图的完整呈现与施工品质的一致性。1号桥不仅仅是一座桥，更是一个宣言、一个起点。未来，和畔皓森将继续在这条融合 “数字之智、生态之美、地域之魂” 的创新道路上深耕前行，让每一处营造，都成为对“和合之境”的生动诠释，为土地留下恰如其分、与时光共生长的当代印记。▼在地打印，Print on site ©和畔皓森+ORS Studio

Bridge No.1 is not merely a bridge but also a declaration and a starting point. Moving forward, HOPE HOUSING is committed to advancing along this innovative path defined by the convergence of digital intelligence, ecological harmony, and regional identity. Each endeavor will be a testament to harmony, leaving upon the land a contemporary mark—one that whispers of its place and grows with the passing seasons.
