［摘要］印象·海南岛仿生剧场是在原“海口水世界”原址上进行改建和扩建而成的，原结构看台蓬罩为悬挑13m的平板网架结构，本次按照改建和扩建的使用要求，需要悬挑25m。结合整个“海胆”的结构形态，采用7点定位技术找形6条六次抛物线，形成前后拱，巧妙地将前后拱隐藏于“海胆”内，使结构从原来的悬挑结构演化为桁架支撑拱壳结构。结合概念设计和计算分析，对桁架支撑拱壳结构体系进行系统分析，并确定了最终结构布置方案。阐述了为满足结构性能设计目标所采取的分析方法和施工措施。

Abstract: Impression Hainan Island Bionic Theater is rebuilt and expanded from Haikou Water World. The original stand canopy is flat\|panel grid structure with 13m cantilever, and the new cantilever is 25m for the using requirement of renovation and expansion. Combined with the sea urchin structure, using 7 points positioning technology for form finding of 6 curves six times parabola, the front and back arches are hidden within the sea urchin, which makes the original cantilevered structure evolve to truss supported arch shell structure. Combining the conceptual design and calculation analysis, truss supported arch shell structure system was analyzed and chosen as the final layout of the structure. The analysis method and construction measures were expounded to meet the needs of structure performance.

Keywords: bionic theater; form finding; truss supported arch shell; six times parabolic
