Abstract

Abstract

In the context of urban development shifting from incremental construction to stock renewal, the utilization of spaces under viaducts can not only revitalize inefficient urban spaces but also contribute to refined urban management, as well as high-quality and efficient construction. Taking the spaces under under viaducts in Chengdu as the research object, this paper explores the strategies for optimizing and regenerating urban viaduct spaces from the perspective of catalysts. The old and new elements reinforce and complement each other to improve the existing urban functions and fill structural gaps. Based on the characteristics and utilization of the spaces under viaducts in Chengdu, the tactile medium is shaped from four perspectives: spatial, functional, cultural, and landscape. Optimization strategies are proposed, including spatial form reconstruction, integration of various functions, expression of urban culture, and creation of distinctive places. Through diversified micro-interventions, this paper aims to transform these spaces into catalysts for urban development, thereby driving the growth of surrounding areas.
