地下街道界面形态特征空间评价研究

RELEVANCE STUDY OF INTERFACE MORPHOLOGY AND SPATIAL EVALUATION OF UNDERGROUND STREETS

相比地面建筑,地下街道存在改造困难、界面压抑等问题,需要更加系统的方法进行设计和评价。通过对多个城市地下街道实地调研基础上,总结了地下街道界面形态的相关数据和类型,建立模型场景并通过VR展开空间认知试验获取相关评价数据,利用Logistics函数模型回归分析地下街道界面形态与空间评价的相关关系。研究结果证实了地下街道视域面积、视觉聚类系数等形态要素与人在地下空间中的体验有着较强的关联作用。

Compared with the ground building,there are some difficulties in the underground streets,such as the difficulty of reconstruction and the interface depression,so it is necessary to design and evaluate the streets more systematically.Based on field investigation of underground streets in several cities,the paper summarized the relevant data and types of underground street interface morphology,built model scenes and obtained relevant data through spatial cognitive experiment under virtual reality,and used the Logistics function model to analyze the correlation between the morphology and the spatial perception of underground streets.The results confirmed that the horizon area of the streets,visual clustering coefficient and other morphological elements had a strong correlation to the man's experience in underground space.
