岭南清代古建筑绿绮楼 安全评估及游客流量控制研究

Study on Safety Assessment and Rational Control of Pedestrian Flow onLvqi Pavilion in Lingnan Area built in Qing Dynasty

摘要:

始建于1850 年的可园绿绮楼是一座高为10.008 米的两层楼阁，青砖墙体和红砂岩石柱为主要承重结构。现在，部分墙体出现微小的裂缝，部分红砂岩石柱有肉眼明显可见的裂纹。本研究的目的是为实现可园绿绮楼的长久保护和合理开发利用 ; 本研究根据结构勘测成果建立有限元模型，进行有限元仿真分析计算，评估结构当前的承载能力，找出结构设计的不合理位置，同时针对人群荷载对结构的动力影响展开研究，在安全性和舒适性都得到保证的情况下，找到参观绿绮楼游客的合理数量；研究结果表明古建筑绿绮楼满足安全性、适用性的要求。本研究结果为岭南清代园林古建筑的保护和合理开发利用提供借鉴。

Abstract:

Lvqi Pavilion is a two-storey structure that is built in 1850 and have 10.008m high, the main load-bearing structure are brick walls and sandstone columns. At present, there are small cracks in parts of the wall, and parts of the red sand rock columns have obvious cracks. To protect and develop the pavilion, the structural finite element model that is based on the surveying and mapping is established and then be calculated and analyzed, the current carrying capacity of the structure is evaluated, the unreasonable positions is found; at the same time, this study will struggle to analyze and study the influence of crowd load on structure dynamic, the reasonable result for pedestrian flow control under the guarantee of both safety and comfort will be found at last; the result show that Lvqi Pavilion meets the requirements of safety and applicability. It proves that the research can provides casefor protection and rational development of ancient architectures of the Qing Dynasty in Lingnan area.
