河西走廊楼阁建筑承重结构安全阈值研究

A Study on Security Threshold of Load-Bearing Structure of Traditional Pavilions in Hexi Corridor

河西走廊楼阁建筑数量众多、类型多样,承载着珍贵的历史信息。不同使用功能的楼阁建筑高度高,荷载值大,其安全性和稳定性需要特别重视。在西北地区恶劣自然环境影响下,河西走廊楼阁建筑承重结构自身易于受到侵蚀和破坏,由于相关规范中对残损点的确定尚不清晰,较难科学评判楼阁建筑的安全性能以及开展适应性的维修工工作,十分有必要结合本地区保护工作的实际情况,开展河西走廊楼阁建筑承重结构的安全阈值研究,为科学化、定量化保护服务。

Traditional pavilions of Hexi Corridor are numerous in quantity and varied by types,carrying valuable historical information.The pavilion is high with heavy loads.Its safety and stability need special attention.Under the influence of the harsh natural environment in Northwest China,the load-bearing structure of the pavilion in the Hexi Corridor is vulnerable to erosion and natural damages.Because the determination of the damaged points in the relevant norms is not clear,it is difficult to judge the health status and conduct the maintenance work scientifically.It is necessary to combine the actual situation of the protection practice in this region to research on security threshold of load-bearing structure of traditional pavilions in Hexi Corridor,providing reference for the scientific,quantitative protection.
