促安全目标下建筑集群全景敞视作用量化研究

Quantitative research on panoptic power of building clusters for safety promotion

全景敞视作用是能够高效提升城市安全的途径之一,本文以全景敞视理论为依托,以促进城市安全为目标,通过综合分析,将城市中建筑集群对外部空间的全景敞视作用归纳为两种类型:场地全景敞视和界面全景敞视.采用空间可视度分析和空间视域分析作为研究方法,构建建筑集群全景敞视模型,实现对建筑集群中全景敞视作用的量化,从而为科学评价城市安全提供新角度,为进一步确定公共安全薄弱区域提供新途径.

Panoptic power is one of the economic and effective ways to improve urban safety.This paper takes panopticism as the theoretical basis and aims to promote the safety of building clusters,and summarizes the two types of panoptic power:site panoptic power and façade panoptic power.By using the research methods of visibility analysis and viewshed analysis,the panoptic power model of building clusters is constructed for quantification,thereby providing a new perspective for the scientific evaluation of the public safety in the panoptic aspect and further offering new ways to identify weak safety area in building clusters.
