摘要:主题乐园与常规民用建筑相比，具有占地面积大、建筑类型多、涉及专业广等特点，需要引入BIM技术解决常规二维设计无法解决的问题。本文主要从基于BIM的大型假山辅助设计，进行方案推敲与多专业协调; 针对复杂游艺单体，以游客视角进行沉浸式体验分析，对投影设备路线进行模拟，优化土建设计和包装设计，确保座位布置合理; 对入口区仿古建筑进行精细化模型创建，利用BIM模型进行人视角漫游分析，辅助建设单位进行设计决策; 考虑园区整体性，对市政管线、单体空间关系、花车巡游路线、设备运转安全等方面进行分析，保证游客的游园感受; 运用BIM技术，全员参与，协调全专业，综合考虑美观、功能与安全等因素，确保设计问题得到充分思考、妥善解决，提升效果品质。

Abstract: Compared with conventional civil buildings, theme park projects possess characteristics of large area, numerous types of buildings, and involving a wide range of specialties, so it is necessary to introduce BIM technology to solve problems that cannot be solved through conventional 2D design methods. Taking a BIM-based large-scale rockery design as an example, this paper carries out the project deliberation and multi-professional coordination. For complex entertainment units, immersive experience is carried out from the perspective of visitors, the projection equipment routes is simulated, the civil engineering design and packaging design are optimized, and the seating arrangement is ensured to be reasonable. Fine model of archaic buildings in the entrance area is established, and BIM model is used to roam through the human perspective to assist the construction units in making design decisions. Considering the integrity of the park, this paper also analyses the municipal pipeline, the spatial relationship of the individual, the tour route of the float, and the safety of the equipment operation, so as to ensure the best visitors'feeling of the park. Through applying the BIM technology, full participation, and coordination of professional measures, and considering of aesthetic, functional and safety factors comprehensively, design problems are fully considered and properly solved, which certainly improves the quality of the effect.
