摘要
冰壳结构是一种以冰、雪为主要施工材料建造的空间薄壳建筑,具有材料易获取,造型丰富美观的特点,在冰雪产业和极地开发领域具有较大的应用前景。为促进冰雪建筑结构在我国的推广和创新,提出了大跨度冰壳结构的设计建造一体化技术,主要从结构热力耦合分析、气膜模板形态控制、喷射施工仿真及结构响应监测等4个方面进行阐述,总结了冰壳结构设计与施工关键技术环节;结合近几年开展的大跨度冰壳结构典型工程案例,介绍了设计施工关键技术在冰壳工程中的应用。相关研究成果可拓宽冰雪建筑的建造规模与结构造型,实现大跨度冰壳结构科学施工与安全评估,也可为制定冰壳结构设计建造标准提供理论与实践依据。
The ice shell is a spatial thin shell building constructed with ice and snow as the main materials.Ice and snow are easily obtained and fabricated,produce no pollution,and are visually appealing.Therefore,ice shells play an important role in the ice industry and cold regions.In order to promote the innovation of ice shell structures in China,the integration techniques for the design and construction of large-span ice shells were presented.The key techniques were summarized from four aspects:thermal-mechanical coupling analysis,shape control of inflatable formwork,simulation of praying construction and structural monitoring.The application of key techniques was introduced based on the typical engineering cases conducted in recent years.The research results have broadened the appearance modeling and building scale of ice structures,realized the scientific construction and safety assessment of large-span ice shells,and provided theoretical and practical bases for the formulation of design and construction standards for ice shells.
