RESEARCH ON THE OPTIMIZATION OF EVACUATION PATHS OF PUBLIC SPACE IN EXHIBITION BUILDINGS BASED ON TOPOLOGICAL RELATIONS

本文针对展览建筑公共空间安全疏散路径优化问题,借助拓扑关系研究方法,探索设计过程中有效评价和优化调整方法。从安全疏散视角对其公共空间构成进行研究,运用拓扑关系将空间“图像”转化为“关系”,建立疏散路径的拓扑关系图解,进而探讨其公共空间构形特征与安全疏散路径属性的关联、同构特征和规律,提炼出基于拓扑关系的展览建筑公共空间疏散路径优化分析方法,即“图像—关系—图像”闭环分析方法,并对建筑空间构成进行反馈与优化。为疏散模拟量化提供了研究基础,为建筑安全疏散问题解决提供了依据。

Aiming at the optimization of the safety evacuation paths of public space in exhibition buildings,according to the research method of topological relations,the effective evaluation and optimization adjustment methods in the design process are explored.From the perspective of safety evacuation,the composition of the public space in the exhibition buildings is studied,with the topological relations to convert the"architectural image"into"relations",in order to establish topological relations of the evacuation paths.On this basis,the relationship between the structure characteristics of the public space in the exhibition buildings and the attributes of the safety evacuation paths,as well as the isomorphic characteristics and laws,are discussed.Then,the optimization analysis method of evacuation paths of public space in exhibition buildings based on topological relations is extracted,that is,the closed-loop analysis method called"image-relations-image"to feedback and optimize the spatial composition of the building.It provides a research basis for the quantification of evacuation simulation and provides a basis for the solution of building safety evacuation problems.
